PHP Paypal Verification

Question

So I'm new working with paypal, the problem I have is that I don't really know where to start, this is what I have to do: My client wants to give lessons, so he customers will order lessons, and they have to specify a date and a time, and if it's available he can make the payment, what is the easiest way to do it? Assuming the customer is logged in, all I need to do is once the payment has been sent accomodate the lesson into the database, can I do that with just paypal "Pay Now" buttons? Or do I need other library? All I know is that paypal "Pay Now" button can redirect you to a "success" url but that's it. What should I use for this? Is there a library or something?
