If you use the search function, you'll be able to find info on several electricians out there that can do this. The things that will likely drive the cost the most will be where your garage is in relation to your electrical panel. If it's far away and through several walls, running the 240 Volt wire will be more challenging, and the amperage you want to charge at will be a cost factor, because wire that can handle 80 amps will cost significantly more than wire that handles 16 amps (which so happens to be the range those cars are rated for) The higher the amps, the faster the charge.
