Asp .net expert needed, sendmail implementation via script

Hi, we need an expert asp .net programmer (sql dbase) to help us with a fix. Need you to work from now till when it's done, perhaps a 4-6 hours job for someone skilled. We already have done a microsite, with user registration, temporary password email, and forget password email, as well as when admin approves their submission they get a notification email. We use standard sendmail and defined the mail servers in web.config. Client wants us to integrate with their mailer api which is a script residing on their server. We need your help to "convert" our forms to work using their system. They have provided instructions (attached) and a previous reference project which has forms and uses the system. We will provide our entire project files, admin files and dbase sql dump. [login to view URL] Thanks.
