Eeef... I'd go with option 3 if I were you and your friends, DS!
Hi all. I'm currently exiled to my study while hubby does some finish work on the painting in the living room. Wow... it's amazing what a coat of good paint (and primer) can do to walls and trim that had been painted in cheapo paint by what undoubtedly had to have been a drunk guy posing as a painter when they built my house.

He was in a major hurry, too. The uneven paint and the drips on the doors made that obvious!
Looks so much better now! But then I'm in the study (avoiding an asthma attack triggered by paint fumes/allergy) and the cats are all locked up so they don't get into paint or underfoot and it's been a LONG day! Still, it's cheaper to do it yourself than hire someone.
