a2billing merchant integration

If you don't know what a2billing is, don't waste your time. you have to have experience in a2billing and know how it works to integrate [login to view URL] as a merchant account and to start accepting credit cards. the API developer guide for myvirtualmerchant can be found here [login to view URL] the admin must have the choice to switch between onsite/offsite credit card processing. so if I want to process all credit card payments on my own website, then I would login to the admin side of a2billing and choose onsite processing, then customers enter their credit card information and all this info gets saved on my servers. but if I decide i don't want to process any payments on my own servers, then i can choose offsite processing from the admin side, then customers who come to pay their bill, will be automatically forwarded to myvirtualmerchant page to process the payment, then taken back to my website after payment is processed. test merchant account already created, so once i award a bidder, i will give you the test account credentials. after creating the integration, plz include step-by-step instructions guide to install/configure this integration module. no outrageous bidders plz. full agreed payment will be in milestone once we award the project, but no payments or even partial payments will be released until this project is completed 100% and fully functional as expected. good luck
