Your best bet would be to go with your state bar's attorney referral service. In order for an attorney to be on the referral list, they have to be competent in their area of practice and be an upstanding member of the state bar. You can also go with your county bar association, which is more focused on your area and will probably yield better results.
I have provided links to these referral services below. They will give you a good place to start. Then you can call the numbers they give you and judge for yourself who you think is best.
From an adjuster's point of view - there is no such thing as a multiply by 3 rule. Basically the adjuster will make you an offer based on the severity of your injuries, your treatment, and pain and suffering will be based on a combination of those things as well as any permanency issues - and if it had an affect on your life. You were on a motorcycle, you obviously have more than just "soft tissue" injuries - and have racked up what about $16-$17K in special damages (plus any wage loss?) if it's a good insurance company, they'll make you a fair offer.
Just FYI - if they do make an offer, it is always up for negotiation - just know your arguing points. Make your case. If they can justify an increase in the offer, then they will increase the offer - so make VALID not generic arguments. AND say the insurance company does make you an offer and you don't like it, so you go get an attorney, chances are you won't get much more than if you were to negotiate it yourself - and the attorney will take anywhere from 25% to 40% off the top - do the math - you'll get more without an attorney no matter what you settle it for.
