VS Studio 2008 MasterPage help

I've build a 200+ page information site in FrontPage 2003 and want to upgrade it to Visual Stdio 2008 (I have the program). I've learned how to have multiple sitemaps but am having trouble with collapsable DIVs or Panels. Also I would like to have an internal site search plus a file download user option. This site of mine is a reading site - information - so I want the left nav and top logo panels to be collapsable by the user. The conversion from FP 03 to VS 08 is what I can do but the MasterPage setup is getting me down - things are not working soon enough. This should be easy $$ for a good .net programer.
