61419 PHP Shopping cart Customized

I have a shopping cart called "Quick Cart" It is 90% finished. Its live already. [login to view URL] I need a PHP programmer to customize it. I have attached the shopping cart. All I need done is this. 1. UPS & USPS Shipping integration. 2. Products need to have option of weight for "shipping".. example: Product 1 is 20 lbs so the shipping is $34. Prod2 is 5 lbs so the shipping is $14 3. At the Checkout screen I need a Credit Card input area that sends all information to the MYSQL DB. for security reasons. 4. Product options. example im selling a pocket pc. I would also like to have an option on that page to sell , screen protectors and leather case. Thats it!
