Add wordpress to my old website (.asp) - making wordpress the new home page yet keeping all other pages safe

Ok, here is the deal: I have bought out my partners on a site that used to make us a lot of money. It has sat dormant now for years unfortunately. I want to add wordpress because of ease of use. The current design is very difficult for me to design and make changes to. site: gameguidesonline (dot) com What I need: 1. A new wordpress home page that will keep the same URL as the current site. [login to view URL] (I know we can use the permalinks to do this.) 2. Keep all the other old pages intact - I will just link back and forth to them from WP. 3. The theme to be very similar to the look of the original. We can use flexibility 3 (i have the paid version) or any other theme you would like to use. So, please post any and all questions plus your bid. Also, how long it will take. Thanks!
