Fedex API development

We need to develop an application using the Fedex Ship manager API which allows us to upload or day's shipments to Fedex. This upload would be done from our head office. The shipment data will be provided in flat file format - i.e. a csv or txt file. We will need the API application to be able to print out the shipping labels at our despatch office located elsewhere. This office has access to our head office through Windows 2000 Terminal Server. I'm looking for someone who is familiar with the Fedex API who could build us a solution.
