The yellow pages are full of lawyers... You don't really need one who specializes in cycling, any personal injury lawyer will bend over backwards for an easy case like this.
Go have a free consultation with a couple of them.
If you want to screw the guy and/or try to enter the judicial system lottery, then pick a snake that tells you how rich you can get (translated to he/she gets rich too).
If you just want to get your bike replaced and medical and legal bills paid, then pick a lawyer that leans toward a negotiated settlement.
It depends on your objective. As a fellow cyclist I hope you lean toward a negotiated settlement.
