I have my own dedicated server for all my proxies (Athlon64 3800+, 1GB RAM), so there is no cost to me to run these sites as I have many other sites which already pay for the server fees. For a person who does not have a dedicated server, my advice would be to go for a VPS as this will be cheaper.
1 Month of FREE web hosting at my server is included for free, so you could save some money buying these sites.
Minimum offer: $500 for two sites
BIN: 900$ (approx 11 times current months income)
Sedo escrow, Escrow.com (if buyer willing to pay their fees), Western Union, Egold, Webmoney. You can offer other payment method.
Please PM me your questions and post your bids in the thread.
