Don't know of any brokerages either, sorry. But... here's a list of local business associations to check out / join.. they have definately made a big difference on my biz.
-- local rotary
-- City (or County if small county) Chamber of Commerce
-- BNI
http://bni.com - Business Networking International, there are local chapters all over the world, and it
works
Yes, these do require some legwork and to goto meetings and hobnob with other business owners... but (but wait! Business owners make IT decisions, like, I need it fixed, new stuff, upgraded stuff!!!) - so it's worth it. Good luck!
