529751 TomatoCart Debugging

i There, I am looking for someone who can make themselves familiar with an open source shopping cart known as TomatoCart (download from [login to view URL]). I am looking to get many modules designed as we have many requests from our customers however, they are quite simply beyond our capabilities. The person who takes this task on needs to know HTML, PHP, Java, CGI & Perl scripting. The problem involves entering information into a product within the control panel and sometimes (not always) the Tax Class & Manufacturer assigned to that product will just reset itself when you save the product. I need this problem to stop happening and it is essential I know how to fix it as it is happening on multiple websites so I will require you to show me. I am happy to provide a test server with the current problem on so you may test a solution. Please see the attached word document for absolute detail. Our expected delivery time will be within maximum 7 days. Once we have seen something like this can be done, we will be interested in plenty more things!
