My client has a fedex module in his osCommerce shop but wants to switch to UPS. He has an account and will need to setup "dimensional" shipping module so that his site will "communicate" with UPS and charge the correct shipping based on geographic location, weight and dimensions of package. Please do not "guess" at this one. You should have experience with adding complex shipping modules / contributions specifically with osCommerce. I will reject any bidder who does not have specific experience with this exact type of work.
