Filmmaking / Directing : Hi Guys by Kev Bolus

I'm a sound designer / mixer & producer from the UK and my family are considering moving to the states to be near family. Can anyone direct me to reputable and high quality audio post production houses that I may be able to make contact with. I'm looking at Ohio, and in particular around the Cincinnati area Many thanks for any help on this Cheers Kev www.kevbolus.com
