Virtuemart Job by samcosmic

It's a VM project but a little different than usual. The website is for an international personal shopper. The customer will enter in the website all the info about the product they want us to buy for them from other stores. We are using a breezing form so the customer will input name, product url, model, size, weight and price. We also got this plugin http://docs.polishedgeek.com/wiki/display/BF/VirtueMart+Breezing+Forms+Plugin+PRO+Documentation;jsessionid=6B139368EAA22FA3B1852C8B92E2B2E1 so the inputted info will be send to the cart. That is kind of working. Product name, url, model, etc are sent to the cart but the price is not. The plugin maker sent me a code to fix that but it's not working and I need help with that. Another problem that came after that - it's the shipping calculation. So basically - it's an order entry with product info, weight and price inputted by the customer (website user/frontend). After register the weight and price, there are 2 calculation to be done - one if fedex and the other if usps. The calculations should be done item by item as the customer may choose to receive one item by fedex and another by usps. I have the formulas for those calculations. Please feel free to contact me if you need more info. Thanks!
