I have software for online selling. Customer can download software and try it on their computer. If he wants to use all features, he must purchase licence. I am seeking for developer who can create payment process on my web site. After successfully paying, some data like customer name, phone number, product ID etc should be automaticaly saved into MySQL database and email should be send to client with product's activation number.
Web site is programmed in PHP and I have SSL certificate.
I need a functional "example" where I can change the sql strings and server parameters, upload pages into my site and try all is working.
Please see attached file for more details.
