Don't get so hung up on "3 tier" and stuff like that.
You have a very specific problem you are trying to solve so just focus on that alone.
What you need to do is run a query against your database to check if a value exists. That's it.
public bool UserNameExists( string username )
{
   // Connect to your database...

   // Run a query to check if username exists. 
   // NOTE: Use a paramatarized query.
   // Something like: SELECT count(*) FROM [YourUserTable] WHERE [YourUserNameColumn] = @username
}
I wasn't, now I am, then I won't be anymore.
