Buy eBuy Shop with good reputation

One of my clients looks for a few USA based eBay shops to buy (from 1 to 50 shops) They sell retail goods and need an option to expand there network. Would also be willing to do cooperate with working shops and get some category in them to sell our products from, shop should exist more than 3 years, with good reputation and option for unlimited products would buy also shops that are not active for some time Payment Via GAF escrow only Thank you,
