River Rock Trade approached our small business in January. The premise is they broker between small businesses for barter services. great concept although when we tried to redeem all the bartering we gave out $500 worth they could not give us any of the things we were looking for..but the worst part if they just stopped emailing or calling us back. we tried for 2 months to redeem what we gave out! not sure if this company is a fraud but it certainly seems that way. we are out $1150. $500 services and $650 sign up fee. Be careful if they come to your small business!
