We hired Patrick Knight to paint a LARGE kitchen (20' x 20'). He did it in oil-based for durability/washability. He had a full crew-- 4 to 5 working at a time. They colored the primer the same shade as our paint choice. The guys were prompt, polite, and professional. The paint job was quite good overall...they got a bit on the floor, but everybody knew that we were about to have a new floor floated over that. I must say that between spray painting outdoors there was a fair amount of equipment and processes involved. We will hire them again. I understand that they also install windows.
