I have a website that needs the payment processing finished. The original webmaster did a good job with the site, but ran into trouble when trying to complete the payment process through PayPal. Another webmaster who did not want to take the job due to lack of C# and ASP.NET experience said that I would more easily solve the problem by dumping PayPal and using Authorize.net for payment. That is fine with me if you recommend it. The site operates as follows: the customer reads the text and takes the quiz for free. If he chooses to print one certificate, payment of $19 is made. If unlimited certificates for one year is chosen, the price is $38. Before the client can print the certificate, a course evaluation must be made. Obviously, the point of this job is to make sure the certificates are released automatically after payment is made so I don't have to do it manually. Please read the attachment with the last three emails of the last webmaster as well as advice about using something other than PayPal. I want to put a three week deadline on this project. The site is written in C# and ASP.NET I am told.
