DMA Radius integration with Quickbooks and Netcash

I am looking for a freelancer to help us integrate DMA Radius, Quickbooks, and Netcash. Specifically, we need the invoices to sync on a regularly scheduled basis, occurring once per month. We need help setting this up so that all three systems are integrated seamlessly and correctly, allowing us to have accurate and reliable data in the future. This integration should be made quickly and efficiently so that our operations are not disrupted. The right person for the job should have experience with all three systems and be able to build a process that works over the long-term. We also would like the integration to allow you to only work off one system instead of multiple e.g. we should process data on DMA Radius and it should load that same data in Quickbooks and Netcash.
