If you have no injuries or damages for which you can be compensated, a lawyer very likely isn't going to be able to help you, or even interested in trying. Oh, you can hire one, and try, but it'll cost you a lot of money and probably not be worth the trouble in the end.
On the other hand, if you have injuries and other demonstrable damages and want to go after the person's insurance for compensation, a personal injury lawyer will usually represent you on a contingency basis and can be very helpful. (It is generally true--in California at least--that personal injury settlements negotiated using attorneys tend to be substantially higher. Sucks, but it's true.)
If you are going to go this route, get to a doctor and get your injuries treated, documented and photographed immediately (you can do this yourself, use real film, not digital). You will need this stuff later. It is really hard to make a convincing case for compensable injuries if you don't bother to get treatment.
But, on the other hand (have I run out of hands yet?) if all you have is a little road rash, you might decide it isn't going to be worth the hassle. In that case, you might just want to continue to get some action from the police to at least try to get the person cited. (I have seen cases take months, even years to resolve--of course this depends on the facts and the evidence and lots of intangible factors, every case is different.)
I am NOT a lawyer, so this is NOT legal advice, just some things to consider. I was a paralegal for fifteen years for a personal injury attorney, worked on quite a few bicycle/auto cases. And some of this will vary from state to state, too, depending on different laws.
