ASP/HTML Login page

We have a simple login page which we have paid someone to redesign the page in html. We now wish for that redesigned page be implemeted so that the login functionality works correctly. We have exisitng branded login pages which work, and have tried to intepret the code, however it is not our skillset. We need someone who is a guru at ASPX and can take a look at both a working login page and then take the new design and apply the right code to allow it to function correctly. It would be a pretty simple job for someone who knows this stuff. I can supply the Branded page and reference sites etc to the winning bidder.
