I sell hard copy products e.g. 3CDs and a printed workbook. I send them around the world.

I know of www.Kunaki.com however they only do single CD jewel cases. Do you know of a company who can provide me with a similar print on demand fulfillment solution to Kunaki however one that can cope with a more varied range of products?

My dream solution:
- UK & US operations so when an order is placed it can be fulfilled by the nearest fulfillment house
- The company can integrate with Infusionsoft
- It can cope with one click upselling so that if a customer buys 2 or more products it goes in one package

Infusionpros tell me that if I can find a company they will work out how to help me integrate it into my account, has anyone had an experience with them?
