Single Sign_on

I have two .Net websites having separate databases for login details. I want the single login form for both the sites. If a user logins in one website, he/she can also access the second website without login. I want a freelancer who can develop two test websites (no design required) and implement the single sign on with a single user table in the database. The code should be well commented so that I can integrate it in my websites later. It should be in ASP.Net 2.0 and SQL Server 2005. Please bid if you have experience in ASP.Net 2.0 and SQL Server 2005.
