CivicRM payment processor

Hi, I got website up and running using Drupal and CIVICRM. I need some one to write the payment processor for civicrm. The payment processor will do form post with details, e.g. credit card no, merchant id, success result url, fail url, etc. Then, on the result url, it will send receipt via email to whom successful registered. Please bid only if you can start immediately and able to complete within 1-2 days.
