77550 Old Ladies Repair

I need some custom work done on my auction site. I need the following added to it. 1. Schedule auction start times when listing an auction. 2. Program has a bug that allows bidders to bid against themselves. If I place a bid for $1 and later decide I should have bid $5 the program ups the bid amount? 2. Bug inside the program that it will not allow users to view auctions past 30 days inside the MY closed auctions. When you enter 30 days to view MY closed auctions you will get 130 ended and 6 pages to click through. When you enter 90 days you will get 400 auctions with 16 pages to click through but when you click on page 2-16 it defaults back to the past 30 day of MY closed auctions. 3. A new header page for each category and subcategory. Right now there is one header page for all page views. I wish to have a different header page per each category and subcategory. 4. The program has the ability to allow users to post classified items. I want the change the process of listing the item and appearance of the item. This will involve creating a new listing page and item view page for classified items. You can see the program used at [login to view URL] and the author of the program with a working demo at [login to view URL] Please DO NOT contact the author with questions about this project unless it is something to do with the program itself.
