I specialize in OSCommerce MS 2.2 and CRE Loaded 6.15 & 6.2. I can have you cart up and running in 2 days. I have a great template that I think would be perfect for your site. I also will give you a users manual on CRE Loaded (I am the author) which will really cut down on your learning curve.
If you need "hack safe" hosting and secure cart, that is available if needed.
Thanks,
Eric
