feed loader for classifieds

We got geo core classifieds and auction system ( [login to view URL] ) and want the following developed for our website as a paid option. load rss feeds of webshop into database as auctions or classifieds. Before user can add the link and use this too he must buy subscription package for his/her shop, which we will specially create for this purpose. This is also to bypass problems with misuse of the rss feeds. User has ability to choose to add the products from his store into his store on my website with option buy now, which will direct to his/her shop or just get contacted in classifieds ads by all users interested in his products, which is in normal classifieds the case. both options will be different price. Before bidding make sure you read all manuals about developing add-ons for the software used ( [login to view URL] ) If you have proven record of working with geocore before, than you got advantage. Software is smarty framework, and is updated on a regularly base, so we really need this as add-on, which is not overwritten and can be disabled or enabled. I got many ideas for more custom made add-ons, means if you can do this, you can work almost all months on my website(s) and have a regularly income.
