Don't be afraid to ask local car dealerships who does their transports. Many of the carriers are independents and will take on side jobs. You know they have to have insurance, or the dealerships would not hire them. Like the article says, be sure to get everything in writing in advance. The dealership may be willing to give you a copy of one of the contracts they use to hire transports. Remember people's word is only as good as the paper it is written on!
