Fedora 6 upgrade issues

we were notified by [login to view URL] that we needed to upgrade from Fedora 4 to Fedora 6 because they were no longer supporting that older platform. I have had a network admin do the upgrade, but there seem to be a couple of problems they are unable to workout, due possibly to permission issues inside x-cart. One issue is the Import Products feature is no longer working correctly, and when a customer tries to order something the built-in UPS program claims "there are no available shipping methods for my location", even though the location is perfectly fine and worked before the upgrade. So we need some back end technical support to resolve several compatibility issues we've found. This relationship could be ongoing. The budget estimate below is for the above project. The below project is separate and can be on a different time line. Hopefully both issues can be handled by the same company/individual. We are also looking for help in drastically speeding up the search capabilities on our site, which does have about 80,000 products total. Currently the search feature takes as much as 30 seconds or more for our customers. Thanks, Louis Pavlovich
