I recently bought a 3-story, 4 bedroom older home that I want to fix up and
rent out. It has old worn-out wall-to-wall carpets throughout al 3 floors.
My plan is to have the entire interior painted white -- including the walls,
ceilings, and trim. Then have all of the carpeting removed and re-do the
floors.

My question is, could an experienced painter do this type of job more
quickly and for less money by spray painting instead of traditional brush
and roller painting?

If so, are there any easy ways to find experienced spray painting companies?
One idea I had was to try asking apartment complexes who they use since I
think many of them have their apartment units spray painted.
