Need programmer for Silk Screen Shopping Cart

[mbtmd]

I need a shopping cart identical to www.countrywidepromotions.com
Please take a look at the quote feature and note that the final price depends on:
The amount of shirts ordered & the amount of colors silk screened. My client is looking to spend aroung $500. Please email me at [e-mail]

Thanks,

[mbtmd]

I forgot to add that we are currently using sunshop shopping cart. Hopefully all that will need to be done is to modify the existing script.
