New Payment Gateway for Magento

I need a new payment gateway developed for the Magento Commerce product. The merchant credentials must be configurable in the admin section, namely: = Merchant Name = Merchant PIN = Merchant Identifier Please see the attached specification document. The API must be developed according to the specific API, as attached. You must use HTTPS POST with CURL. You must use the MerchantRequest method as specified, NOT the Redirect method. I need this no later than Wednesday, so if you cannot do it by then, do not bid.
