PHP/MySQL Quickbooks Import

We currently use a PHP/MySQL quote generation system. This system creates a pdf invoice based on each quote using fpdf. Inside MySQL is a specific table for each line item of these invoices. We would require the ability to batch export these invoices weekly to a file that can then be imported manually straight into Quickbooks. We are looking for someone who has done this before. The version of Quickbooks is 2003 Pro using Multicurrency and we expect to be using IIF files for the import. All the variables and mysql queries should be easily copied out of the existing pdf invoice script to generate the iif file for whoever does the work.
