You can't inherit a form from a control, it should be from System.Web.UI.Page. Add a usercontrol and move all markup and code to that control:

MyUserControl.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyUserControl.ascx.cs" Inherits="JeremiahTorresportfoliov1.MyUserControl" %>

<div class="focus" >
    <label>
        I need...</label>
    <asp:DropDownList ID="cboConsultationType" runat="server" CssClass="select sub web">
        <asp:ListItem Value="I Need A New Web Site">A completely new website</asp:ListItem>
        <asp:ListItem Value="Web Site Upgrade">My website upgraded</asp:ListItem>
        <asp:ListItem Value="Application Design">An application </asp:ListItem>
        <asp:ListItem Value="Other">Other</asp:ListItem>
    </asp:DropDownList>
</div>
<ul>
    <li>
        <asp:Label EnableViewState="false" ID="lblErrorMessage" runat="server"></asp:Label>
    </li>
    <li>
        <asp:Label EnableViewState="false" ID="lblName" AssociatedControlID="txtName" runat="server"
            Text="Name"></asp:Label>
        <asp:TextBox ID="txtName" runat="server" ValidationGroup="ContactValidation"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidatorName" runat="server" ValidationGroup="ContactValidation"
            ControlToValidate="txtName" ErrorMessage="Name is required">*</asp:RequiredFieldValidator>
    </li>
    <li>
        <asp:Label ID="lblPhone" runat="server" AssociatedControlID="txtPhone" EnableViewState="false"
            Text="Phone"></asp:Label>
        <asp:TextBox ID="txtPhone" runat="server" ValidationGroup="ContactValidation"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidatorPhone" runat="server" ValidationGroup="ContactValidation"
            ControlToValidate="txtPhone" ErrorMessage="Phone is required">*</asp:RequiredFieldValidator>
    </li>
    <li>
        <asp:Label ID="lblEmail" runat="server" AssociatedControlID="txtEmail" EnableViewState="false"
            Text="Email"></asp:Label>
        <asp:TextBox ID="txtEmail" runat="server" ValidationGroup="ContactValidation"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ValidationGroup="ContactValidation"
            ControlToValidate="txtEmail" ErrorMessage="Email is required">*</asp:RequiredFieldValidator>
        <asp:RegularExpressionValidator ID="RegularExpressionValidatorEmail" runat="server"
            ControlToValidate="txtEmail" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
            ValidationGroup="ContactValidation" ErrorMessage="Email address is invalid">*</asp:RegularExpressionValidator>
    </li>
    <li>
        <asp:Label ID="lblMsg" runat="server" AssociatedControlID="txtMsg" EnableViewState="false"
            Text="How can we assist you?"></asp:Label>
        <asp:TextBox ID="txtMsg" runat="server" TextMode="MultiLine" Rows="5" Wrap="true"></asp:TextBox>
    </li>
    <li>
        <asp:Button ID="btnSubmit" runat="server" EnableViewState="false" CssClass="submit"
            Text="Send" ValidationGroup="ContactValidation" OnClick="btnSubmit_Click" />
    </li>
</ul>

MyUserControl.ascx.cs:

namespace JeremiahTorresportfoliov1
    public partial class MyUserControl : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

protected void btnSubmit_Click(object sender, EventArgs e)
{
    bool bSent = false;
    try
    {
        //create the email and add the settings
        var email = new MailMessage();
        email.From = new MailAddress(FromEmail);
        email.To.Add(new MailAddress(FromEmail));
        email.Subject = Subject;
        email.IsBodyHtml = true;

        //build the body
        var sBody = new StringBuilder();
        sBody.Append("<strong>Contact Details</strong><br /><br />");
        sBody.AppendFormat("Needs: {0}<br />", cboConsultationType.SelectedValue);
        sBody.AppendFormat("Name: {0}<br />", txtName.Text);
        sBody.AppendFormat("Email: {0}<br />", txtEmail.Text);
        sBody.AppendFormat("Number: {0}<br />", txtPhone.Text);
        sBody.AppendFormat("Comment: {0}<br />", txtMsg.Text);
        email.Body = sBody.ToString();

        //send the email
        var smtpServer = new SmtpClient();
        smtpServer.Send(email);

        //mark as sent ok
        bSent = true;
    }
    catch (Exception ex)
    {
        //send any errors back
        //add your own custom handling of errors;
    }

    //let the end user know if it was a success
    ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('" + (bSent ? SuccessText : FailureText) + "');", true);
}

//properties    
public string FromEmail
{
    get { return _fromEmail; }
    set { _fromEmail = value; }
}
public string Subject
{
    get { return _subject; }
    set { _subject = value; }
}
public string SuccessText
{
    get { return _successText; }
    set { _successText = value; }
}
public string FailureText
{
    get { return _failureText; }
    set { _failureText = value; }
}

//fields
private string _fromEmail = "info@example.com.au";
private string _subject = "Website Enquiry";
private string _successText = "Thank you for submitting your details we will be in touch shortly.";
private string _failureText = "There was a problem submitting your details please try again shortly.";

}


    }
}

Add this control to your page and fix code.

Contact.aspx:

<%@ Page Title="Contact" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Contact.aspx.cs" Inherits="JeremiahTorresportfoliov1.Contact" %>

<%@ Register Src="~/MyUserControl.ascx" TagPrefix="uc1" TagName="MyUserControl" %>


<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent">
    <uc1:MyUserControl runat="server" id="MyUserControl" />
</asp:Content>

Contact.aspx.cs:

namespace JeremiahTorresportfoliov1
{
    public partial class Contact : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
    }
}

UPDATE: I can see in your update you still have error. Change this in MyUserControl.ascx.cs:

public class MyUserControl : System.Web.UI.UserControl

to this:

public partial class MyUserControl : System.Web.UI.UserControl

In Contact.aspx move reference to Myusercontrol to top of the page like this:

<%@ Page Title="Contact" Language="C#" MasterPageFile="~/Site.Master"  AutoEventWireup="true" CodeBehind="Contact.aspx.cs" Inherits="JeremiahTorresportfoliov1.Contact"%>

<%@ Register Src="~/MyUserControl.ascx" TagPrefix="uc1" TagName="MyUserControl" %>
<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent">
