Modify Open Source VB Shipping Software

The name of the software is Order Integrator- and we have it installed, and working with our CRE B2B site, and Endicia's Dazzle. The basics work well, but it needs some bug fixes, and a new user interface to make it perfect. It should be a fairly simple project- the UI we want is pretty straight forward spreadsheet style instead of the scrolling through individual orders that it does currently. Bug fixes involve issues with default settings (it won't default to our preferred shipping method), and batch printing labels. We would also like a couple of other default settings put into the software (adding insurance for packages over X amount). I'd also like it to report the Algozone Fraud detection score, and to confirm that Paypal payment has been made for an order, and report both of those for each order. We're looking for a relatively quick turn time on this project- we made some changes, but need a decent coder to take it the rest of the way.
