Custom product Virtuemart and Joomla Modification

Hi the fix that I need to do is this, mainly I need something like hack 2.x for Virtuemart but with differences: 1. The main need is create an image/or text uploader so the client can upload and image or text to the base image. Like oscommerce like this [login to view URL] 2. In user registration, I need the system to create a check box (maybe with community builder) that will reads “buyer” “Seller” “buy and sell” WHEN REGISTRATING , if the buyer check the , “seller” or “buy and sell” it will ask them a “storename” the store name will me stored in a folder for example [login to view URL] The products will be shown in the Top category STORES and each custom product will be duplicated for example: the new custom product “t-shirt with reggae picture inside” will be store in the SELECTED TOP CATEGORY (MUSIC/REGGAE or selected category) AND AUTOMATICLY BE ADDED TO THE TOP CATEGORY(stores/storename1) 3. PRODUCT MODIFICATIONS AND CATTEGORY SET:Each user will be able to set in their stored products: a) PROFIT NUMBER FIELD: profit over the base price (if we sell a product+image for 10 and he set profit 3 the custom product will be shown at $13) b) EDIT PRODUCT: On his products, change images and add new custom products Selecting a category and subcategory for each(music/reggae for example), c) REPORT PROFITS:I need also a simple report how much are they getting at the time every 3 months d) NON CUSTOM PRODUCT CHECKBOX: And I need to set a restriction to those products that you can not custom them, maybe a checkbox “this product can not be customized”. 4. If a user modifies a custom product in his list the “clone”product will be modify as well in the associated category Please let me know how much will cost this and the time line
