Normally you could legally do work on any part of the house yourself but since it involves work before the main breaker I'm pretty sure the power company can tell you that the person needs to be licensed. They will provide the electrician with a DR number it's kind of like a work order number that had to be used to get the permits. I think that the $2100 number you got doesn't seem bad especially since there is going to be a sub panel involved and probably running some new home runs to garage. Depending how far the meter is going to be from panel, they may also need to be a main service disconnect at meter and have your main panel act as a sub panel to that. I honestly wouldn't want to mess with all that myself. Ill pm you alittle later.
