Add-on for Geodesic Solutions Auction Site

Hello, We have purchased an out of the box auction solution called Geo-Core from Geodesic Solutions. We would like to have a custom add-on developed for our site. We will only consider bids from providers that have a team of developers that have expert level experience and require little direction after initial requirements are gathered. If you have previous experience with developing add-ons for Geodesic Solutions Auction sites, then please say so in the message you send to us. Must have advanced understanding of MVC concepts and must be able to provide examples of previous work in developing custom add-ons from scratch including advanced integration with Paypal, E-commerce api integration with shipping providers and other concepts such as attribute / category filtered navigation. Please only bid for 1 add-on at a fixed-price.
