Eames 670 and 671 Upholstery Question.  

Hello everyone. I've tried searching this question before and didn't come up with much so forgive me if this has already been answered here. I have recently been gifted from a family member a Eames 670 and 671 produced in December of 1978. While the oiling of the wood and shock mount replacement are within the scope of my abilities, I have no idea what or where to go with the upholstery. Usually I would prefer to keep the original but the seat bottom had an unfortunate split from someone sitting on the chair with a pocket knife in their back pocket and another weird small split in the lower back cushion. I'm thinking it would be best to fully reupholster it in order to avoid mismatching. What is the typical cost of reupholster the cushions from these chairs? Also, if there are any recommendations of quality upholsterers either in San Diego or Chicago (currently attending school in the midwest) it would be greatly appreciated.
