Where to find finishers for new cabinets?

Building my own laundry cabinets and not sure I have the room in the garage or basement to finish the boxes (uppers) so was wondering how one goes about finding a company that does spray finish work. Every search results in refinishing painting services or cabinet makers.

I could spray in place I suppose but was planning on painting the walls, ceiling, and putting in new flooring ahead of the cabinets as those would end up taking me the longest to do.

I'm in Canada (North GTA) if anyone else knows of a place.

Thanks!
