Upload Sales Orders into Quickbooks

I have a real nice sales order application that I'd like to interface with Quickbooks.? I'd like an interface program built which I can call that will populate the sales order database in QB. This needs to do three things. 1. Populate the sales order database 2. Populate the accounts receivable and invoiced databases my application will prepare and invoice sales orders, and then the information needs to get into QB as if the sales orders were generated there as well as the invoices. That also means the inventory transactions need to be updated. I can provide the imported data in any format necessary, csv, access, flat txt file. You tell me and I will provide as well as all necessary data elements. I need the coder to provide me the necessary data elements and stuctures to work with their import program.
