Paint Stripping Pros Recommendations

My wife and I just moved to a 1928 co-op apartment in the east village. We realized how many layers of paint that has been caked on during the years. We were looking to find a professional strip the doors, door frames and window frames and wanted to ask if anyone could recommend a professional who has experience with this.

Would love to get a professional opinion and estimate. We are on a budget, so wanted to get a sense of how much it would cost to do the right way. We really want to keep as much of the apartment in its original state as possible. We have 5 window frames, 7 bedroom/cabinet doors, 3 entry ways and all the baseboard in the apartment.
