57204 Modify Search Engines

I have 3 search engines that use the script from smarterscripts.com. (more information about the script can be gathered from their website). The scope of this job will require making modifications to the Search Engine website to make the following items possible: 1. Correct errors that are being produced when a search is done on them. An example of the error is: [login to view URL] 2. These errors started when my 4th website (which is an affliate tracking website for all my search engines) went down. Before the 4th site went down, everthing was working perfectly. I want to get the sites back up and running so the searches work as they are supposed to. So this project may require correcting the code on all 4 websites (the 3 search engines and 1 affiliate site). I would prefer for you to bid on the total project vs. hourly rate, etc. Any questions, please contact me.
