First off you need to get your insurance problem solved. If your carrier is lowballing you, and it sounds like they are, get this squared away before you do anything else. Then it depends on how much of a hurry you are in. It's like anything, you want it done right now, you will pay top dollar. If you are patient and beat the bushes I'm sure you'll find people who can do it for you to your satisfaction. But I agree with what has been said, this is going to require multiple shops, at least a frame shop and a body shop as a minimum.
