I'm not endorsing any of these, but through a simple google search you'd find these on the BitcoinTalk website.

Both of them seem to have good reviews by people, pretty expensive though so I'd look deep into it and see if this is worth it for you. May I ask how much volume in coins you're trading per day? As that really helps as to if it's worth it to get one of these.
Good luck bud, this is a big buy!
