I'd recommend trying some of this yourself first, before agreeing to send it off elsewhere. My impression of OT.com is that there are a lot of people who will gladly take your stuff, and maybe not necessarily do as nice a job on the editing as you yourself could if you'd only give it a shot. Or, some others (like me) would gladly take your stuff with the best of intentions, but because they've got about 50 projects on the go already, it'll be early 2010 before you see any results back.
It never hurts to learn how to do stuff yourself. If you get good results, awesome; there's one more person around here who can contribute good results. If you're disappointed with the results, too bad; you've still got the recourse of being able to send your stuff to someone else -- but you'll more fully understand the issues, and why it's taking a while, and how tough it might be to get excellent results!
My 2¢, anyway.
