Configure Authorizenet and OsCommerce

Seeking experienced person who can configure and successfully test OsCommerce and Authorizenet (AIM). The current status is: in live and simulated "buying" tests OsCommerce successfully processes requests and sends confirmation emails to the test customer but it does not send confirmation emails to the website owner (me) that a purchase was made. Also, Authorizenet does not record or process the "successful" transaction that is done by OsCommerce, and thus no confirmation emails are generated. I believe that OsCommerce is not communicating with the Authorizenet server. What I need: I want someone who has experience with OsCommerce and Authorizenet (AIM) and who can provide references. Goal: A completed project would be one that can successfully process "purchases" in test and live modes where 1) the website owner receives confirmation emails that a purchase was made from both OsCommerce and Authorizenet, 2) confirmation emails from OsCommerce and Authorizenet are received by the test customer of a pending purchase.
