Why not give them a little competition? You could fill out a DBA statement to register your business for a few bucks, and the Small Business Development Centers throughout the US offer free advice. If they're too far away, you can always get free marketing, accounting, et cetera advice from score.org online.
You might be able to provide a much more cost-efficient service for all (especially if the agencies there are overpriced) and make a few bucks out of it too. I like the idea. I keep thinking about organizations who just meet the requirements and must provide an interpreter, but can't afford to pay expensive agency fees.
I think that'd rock.
