Help for Web Project

[bazigaar_no_1]

hey guys, I'm shortly going to begin working on this new project but I need some info about these things before I actually start :

The website which I plan to make will allow the user/client to modify certain things only if they pay through PayPal. Now, suppose I want $1 for every change they would make. Is there any script that validates that the client/user has made the payment of $1 (only $1 not more, not less) and then and only then can he make the changes ?If I want to make my own script, which language(s) would I need to learn? And for this kind of website, what kind of PayPal account would I need to make ?

Thanks in Advance

Paypal has a API. Take a look at it. You can also try Billing Scripts.

I suggest a Business Account for Paypal

Yes through paypal API you can determine whether payment has been done or not. Paypal returns many info in POST variables after transaction. For every $1 paypal will deduct $0.35 apprx as a fee if you use business of premium acct.
