As already mentioned, KTrain and Russic run
Build Studio and they would be a great place to start. There's also
Armadillo Studios who had a hand in building CP, so also worth a look.
Full disclosure, both Build & Armadillo are run by good buddies of mine, so I'm 100% biased in recommend them.
I'm not sure how far a long you are with your planning/strategy right now, but I'd strongly recommend going with a
responsive site, as more and more people are moving to "mobile only" as their primary internet access. It's my personally opinion that if you're not building a responsive site in 2014, you'll regret it in 2015.
I'm not freelancing myself much these days, but if you have any questions or just want some feedback from some one in the industry feel free to send me a PM.
