There's no guarantee that a private speech therapist is better than one through the county. If you get a reasonable # of hours through the county (at least once/week, maybe 2#/week) and you don't like the person, you could try asking for a different person--we were able to do that in DC without a problem.
One other thing you might think about is introducing some sign language. Having some basic signs can help reduce frustration in a child with a language delay. Look into the "Signing Time" series (there are different ones for babies and older kids).
I agree with some basic signs--like "more, please, milk."
Also as when or if to start private services is completely child dependent.
When they're young, EI tends to give a lot of services/support. If your kid is making progress, there's no rush for private. Progress can be slow sometimes too. I'd give it a few months and then decide if you need to supplement.
