Convert my Yahoo Ecommerce site to Zen-cart/Magenta (any open source shopping cart)

I have a small yahoo commerce website. It has 9 categories and a total of 45 products. I want to stop using yahoo commerce and put it onto a hosted script such as Magenta, Zen-Cart, etc. I want it on a free open source cart that is secure and popular. You will need to download the photos and descriptions for the 45 products and upload to the shopping cart. The design is not important, just transferring all of the products and categories is. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law. Employer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the employer on the site per the worker's Worker Legal Agreement). 2) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 3) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Employer's environment--Deliverables must be installed by the Worker in ready-to-run condition in the Employer's environment. b) For all others including desktop software or software the employer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this project. ## Platform I'll provide linux php hosting, you setup the script and copy over products and get it all setup
