Service Shop Recommendation - Chicago Area

I'm new to this forum so I hope this is the correct area to post this question.

I just purchased a 1978 280Z with extensive engine, drive-train and suspension modifications. I need to find a shop in the Chicago area (north burbs preferably) that is experienced with this type of car and performs quality work. I prefer small specialized shops over large assembly line type operations, but I'm open to all suggestions.

Any help would be greatly appreciated!
