Shopping Cart Migration

We have a client presently using [login to view URL] as their eCommerce solution to sell 6 items. I need someone who can take their existing site and cart off of [login to view URL] and move the shopping cart over to either OSCommerce or [login to view URL]'s shopping cart. The site's pages are presently done in flash and the cart is their basic merchant cart. I would like the existing site pages (3) converted from Flash to HTML. In your response please provide link examples to working, functional eCommerce/OS Commerce/[login to view URL] sites so that I can get an idea of what you can offer. If you have a different cart you would recommend, let me know and provide links to functioning samples. Our maximum budget for this stage of project is $350.00 but we will require an hour or two per month for ongoing cart maintenance.
