Changes needed to a simple PHP site

I have a site that is almost complete. The site was sliced from a photoshop file and coded into an active php site. There is no database used at all so it is a fairly simple php site. I need the left menu (uses javascript mouseover effect ) updated to add an additional link on all pages excpet the main page without affecting current functionality. I need the current picture gallery updated (currently has thumbnails to click to enlarge) to also add buttons so a user can click through each picture (click right arrow to move forward click left arrow to move backward). There a a few minor changes to make to text and additional pictures added - complete change list available and attached. I need this completed very quickly so please do not bid if you can not start work right away. Thank you for looking and bidding on my project.
