Troubleshooting, Install

What I need is to find out why the search box will not bring up any links on my site even after the specific keywords are used in the search. I also need to have a couple of other things fixed on my script. 1: For some reason, I get an error message when I try to upload an image, a banner, or when I try to cache a page. 2: I need to customize the page that shows when you try to add a link. I need it to display the options to either place a link for free, or submit a sponsored link, and pay through my payment gateway. This is already set up, and the script supports it. 3: I need an amazon affiliate search box installed on my site. 4: I need the searchbox troubleshooted to find out why I get no results when a search is made. This should be an easy job for someone that is knowledgeable. Anyone willing to try to fix these issues, please feel free to bid.
