You'll have enough trouble trying to deal with the bankruptcy law as it is, so don't try to save money by hiring a cheap or inexperienced lawyer; instead, hire they most lawyer you can afford. As the old saying goes, you get what you pay for, and that's as true in law as in anything else.
You shouldn't leave your bankruptcy lawyer to handle everything by themselves after you've started the process. Stay involved. Make sure you recheck all the filings, keep track of where you are in the process, and keep your lawyer on their toes.
