Credit Card Processing - SIMPLE!

We already have a merchant account setup. We use [login to view URL] as our Payment Gateway. What we simply need is the code to interact with the gateway from our website (example: customer enters their credit card or checking account information, and other necessary info on our site's secure server, [this is where you come in] then it needs to transmit the information to [login to view URL] to immediately process the credit card. If declined, they get sent back to the original page to to re-enter their info. They can only do this 3 times, before they are taken to our 'Contact Us' Page. If approved, they are sent to a 'Thank You' page.) We understand that you may need some information about our gateway to get this done. After we have chosen you as the coder, we will get any information that you may require to complete this job to you. As a developer, I know some of the code to get this to work, but not all, and that is why my company has asked me to outsource this work, as it is not quite my expertise. So in summary: We need the code to get our website to process a credit card or echeck transaction through our payment gateway. I have already coded the page where the customer will enter all of their information. We need the code to make it all work. If you can deliver before the deadline, that's even better! ## Deliverables 1) Complete and fully-functional working pages in as well as complete WELL COMMENTED source code of all work done. 2) All documents, including source code in .ZIP file, or other compressed format. 3) Complete ownership and distribution copyrights to all work purchased. 4) You must make yourself available after so that when we test, and verify that this works, we can contact you if this is not done the way we need it so that you can advise us of any necessary modifications to the code. ## Platform PHP, MySQL, HTML, DHTML, XML, JavaScript, C++, PERL.
