WordPress plug-in for eBay creation

We need a WordPress plug-ing that will allow featuring specific shops on the blog and possibly searching within specific eBay shops collectively, for example to check stocks within related shops selling the same items. The plug-in must remember the list of shops that we enter (a configurable database, so we can add and remove shops as needed). Or in other words: The project requires finding or creation of the Word Press PlugIn that allows specific eBay Shops to feature within a blog and be searcheable collectively. Another functionality may be a possibility to search the stock and availability within those shops but it's not an absolute necessity. The plug in must rememeber the list of eBay shops to feature them permanently. Other functionalities may be discussed at a later stage. Please quote accordingly and indicate the timescale. Plug In must adhere to all common standards. Opportunity for more permanent position in the future also available. Please, provide your quotes. Thank you Kamil ## Deliverables The plug-in must be easy to use on frant and back and, must addhere to all proramming standards and common practises, so it's easy to modify it and implement it even after WP upgrades. It must come with all necessary description for the next coder to be able to modify it.
