PHP Pro Bid Modifications

I too have a php pro bid auction website I am getting ready to launch and would like to make the following simple modifications: 1) Modify so it shows only categories and subcategories in the menu with items listed in those categories.. 2) Show only additional auction fields that are used for each item, if not used, not displayed on auction detail page. 3) Add auto generated category links to show: Browse by Price $25 and below $25 - $50 $50 - $100 $100 - $150 $150 - $300 $300 and up Integrate php pro bid login with phpbb3 or invsion board (1 login for site and boards) and integrate site design with bulletin board to give seamless look and feel going from bulletin board to auction site. Please advise if you need further information to quote and also advise some reference php pro bid work you have done. Please quote each task/change separately.
