Shipping Label Software

Hi all,

I run a small biz that processes 40-50 orders a day going all over the world. We really need reocmmendations for Windows software that pulls orders from our osCommerce site and spits out labels and order invoices. We've already got our store front (osCommerce with a little dev help is an amazing thing), so I don't need some $1800 a month full website plan - I just need the backend windows software.

Ideally we could poll orders from over a MySQL link to the ocCommerce tables and then print FedEx and USPS labels. The customer would then get an email with tracking #. I really need the ablility to hit a button and have a FedEx label spit out. No jumping from program to program, no importing/exporting CSV files. Just a button.

I imagine there's got to be software out there for this will all the millions of home biz shippers like myself but no luck as of yet.

A few that I've found that don't do anything for me:
Stone Edge Order Manager - depends entirely on third party software
ShipWorks - doesn't interface to oscommerce
NetSuite - looks like it may work, but I feel like I'm way too small for such a gorilla

Does anyone know of a ~$500 piece of software that will handle all the different UPS, FedEx, USPS, DHL type labels? Listen up developers! There is a huge gap in the market here!
