The only way for you to feel like you get a fair price, is for you to get 3 prices from electricians in your area. You will need to define the job. I understand that is difficult for the homeowner to do, but is required if you are going to compare apples for apples.

It's a terrible smell!

Like Dan said; this is something that a person needs to look at to come to any sort of conclusion.
