usps shipping module customize

i need someone to customize the USPS shipping module by categories or products and the shipping prices pull up from the usps website since i have different type of iteams on the store but cant pack in one box and had to make 2 boxes but i need someone that could make it so ill will pull up straight up from usps and get a price of shipping

thank you


its likes usps generates by the categorizes since some products pack in big boxes and some in small box i need something that could seperate it and when the total comes and it combines both of them


thank you

I have an Individual Shipping extension that will group products by manufacturer and display a quote for each them, but I'm not sure if that's what you want.

i need something where it generates from the usps website so i don't have to do extra work for shipping it
