Now all you have to do is put up YOUR money, that you may have to pay interest on. Pay rent on a place to store the inventory. Pay for heat and electric for that place. Get a phone and maybe a web site and hope that you can somehow sell these. Don't forget about the warranty claims and other things you will have to deal with after the sale. You may want some kind of insurance for the ever possible lawsuit. Ebay, paypal and the credit card companies all like to collect their fees. Don't forget about all the time and hassle involved in keeping records for taxes and whatnot. Oh yes don't forget that you have to pay taxes on all of that excess profit.
