UPS Shipping integration

Hi,

I was looking for some ideas on advanced shipping options for OpenCart 2.x

I need the customer to be able to
-enter a UPS customer number upon selection of UPS at checkout
(-enter a FedEx customer number upon selection of FedEx at checkout)
-Ship packages over 150pounds with UPS Freight
-get an accurate UPS pricing for shipping based on address, weight, etc.

Basically, what I need is integration between OpenCart and UPS World Ship for version 2.X.

Ive seen some add-ons but non for 2.x. Any suggestions?

Thank you!
