Magento module

Hello, We are using the extension M2E on Magento to connect Ebay. we needing and magento module/extension which handles the following tasks: - we need the possibility that we could setup different sets of an product with different skus for example we have the item "ledlight" with the sku L-10000 Now we want sell this "ledlight" in different sets for example: 10pcs set get sku L-10010 20pcs set get sku L-10011 50pcs set get sku L-10012 All this sets are related to the stock of sku L-10000 and will only be sold on EBAY. So if we have an stock of 1000pcs of sku L-10000 than we should have: sku L-10010 100pcs stock sku L-10011 50pcs stock sku L-10012 20pcs stock If we import the order of this products from Ebay to magento than should the sku in the order transfered to main product sku including the total number of pieces which we sold on ebay. For example: incoming ebay order: L-10011 "ledlight 50pcs set " order quantity 5pcs should be changed to: L-10000 "ledlight" order quantity 250pcs Shipping: If we are import orders from Ebay then we see only M2E as shipping method and shipper this has to be changed to the right shipping method for the product and the right shipper. Bundle Products: If we are setup bundle products and export them to ebay, than we have the problem after the import of the order that the sum of the product prices are not correct. (dynamic price) http://docs.m2epro.com/display/m2e/General+Settings#GeneralSettings-Simpleproducts "At the moment M2E Pro only supports listing of Bundle Products with Fixed Price. If a Bundle product has Dynamic Price option, the price might be calculated incorrectly." If any further question please write me an PM. Thanks Patrik
