Need an expert with in depth knowledge and experience with PayPal and Payflow Pro. Please do not respond if you have not done at least 3 such integrations with Payflow dotNET SDK. We already have the application that integrates a few other gateways. You will not be building Data base or a front end web page. The ideal solution will include hosted page integration and , Transaction Status inquiry before, during and after transaction completion (within 3 hours and after 3 hours). If this does not make sense then the project is not for you.
