493942 Full desighn and build oscommerce website w eBay intigration

I need full e-commerce site built and design preferably in osCommerce but will consider other platforms with eBay integration. I have eBay account and sell my items from eBay. I want be able copy (import) my items from my eBay account to my store. I want to copy pic + text (description) + weight or shipping charges (if flat or free) + quantity + variations, if any +price and categories. I want to be able to create my product on my site and export it (if decide) to eBay. Or if I create new item on eBay import to site in same category as eBay. Also, when I import items from eBay to site, it should de-activate items on site that are no longer available on eBay. Categories must be created like categories on eBay store! If I modify some eBay store category name or delete it or add any things... then an update must be made on my store automatically. I want to have same categories of products on eBay and on my store. I like to see same categories on eBay and my store. I want possibility to change weight for all products imported from eBay to store. Weight will be used for calculation of shipping cost. Update doesn't have to disturb customer on my website. Website must be still available even if there is an update. Store should simple, easy to use, customer friendly. What I mean? Ok. Site shouldn't have any unnecessary adds, windows, links ect. . I don't like when site has many different distracts. Easy navigate. Customers should be able to check out without registration as a visitor or if make registration, if decide. Select, add payment information, pay and go. Simple. - English language. (USA) - Full PayPal and Google check out integration - Shipping Calculator (UPS, FedEx, USPS and flat rate) Customer must see shipping charges before check out or registration. Calculator bottom should near item(s). -Shopping cart (calculate shipping and price(s) for multiple items. ) - eBay integration (import/export from/to eBay) **preferably integration with craigslist (But not important, can do next time) - Search Engines Optimization (SEO) “Search friendly” - Create discount codes (oscommerce has it as regular option) I will sell liquidation items like clothes, home goods (cookware, small kitchen appliances ect.) I will sell by pies (ea) or lots. Please read carefully this project and place a bid only if you know you can do it. If you have any questions please feel free to contact me.
