LTL rating program

Looking for a secure web enabled (Less Than Truckload) LTL rating program to provide estimated prices on LTL shipments to multiple customers. The program is a zip-to-zip rating program predicated on weight (WT), class (CL), origin and destination zip codes, and a rate-per-hundred pounds. To this a customer-specific discount is applied and a shipment specific rate is provided. (If you go to virtually an LTL carrier such as [login to view URL] or [login to view URL] you can use their on-site rating program to see how they work in detail). I have all the rate/class/wt/zipcode databases necessary to operate the program. I have screenshots available (but am unable to upload??) Please note that this is not a request to develop a program to gain access to the carriers websites via API to use their rating programs. What I am looking for is the ability for my customers to go to my website and logon via secure username and password to get rates that reflect their individual discount programs for an LTL shipment. Each customer has a specific discount program that is individual and specific to them.
