eBay sniping site repair

I have an eBay sniping website that needs a little work. At first, the problem was just that when someone entered an eBay item # for an eBay motors item, my site would say that the item was not found. Now, my regular programmer modified the script and now when any item -- not just eBay motors items -- is searched for by item #, the item information(auction title, ending time, current bid) is not returned and then when a snipe is set up for that item, it does not execute. However, when an item is searched for by keyword phrase, then a snipe can be set up for the item and all the information will show as it is supposed to, and the snipe will execute. You would probably have to chat with my regular programmer to get a good idea of what is going on and get up to speed on the code. He may continue to work on it as well. I just need to get it fixed. I would also like to set up some sort of ongoing error checking script of some sort to make sure that the script is working properly. I also need someone for ongoing maintenance to the site, whenever an error occurs that prevents snipes from executing, I need it fixed as soon as possible. The script is written in PHP, on a Linnux server. Because it would probably be hard to judge how long fixing the script would take, I would say make your bid for five hours of work. As I mentioned above, if things go well, I also like to find someone for maintenance for the site.
