A lawyer won't really help you get more money. Lawyers get more money from the insurance company to pay themselves. If you are having a problem getting fair treatment from an insurance company, either threaten, or actually make a complaint to the DOI (Department of Insurance). Nothing will get an insurance company's attention and reaction faster, not even a lawyer.
When Gloria's sister and mother got t-boned by a drunk driver who ran a red light. Every single lawyer her sister called refused to take them on because the guy didn't have insurance, so there were no deep pockets to go after. They eventually found a lawyer, but they are still just as much shit out of luck as they were before.
