[Skunkworks] wifi expert

Any wifi experts out there that can help us with our office network? We need the network to be able to handle 300+ simultaneous wifi users on three floors of our office building. Looking for someone who has setup wifi networks of a similar size and knows how to deal with interference issues and optimal placement of APs. Want someone with proven track record of similar installations. Please inbox me if you are interested or if you can recommend someone. Josh
