Alternative idea for ya Boom.
On an episode of mythbusters, Adam built a steel box to paint a room. He set the box in the center of the room making sure the sides of the box were parallel to the walls.
He put a paint bag on each of the sides of the box and loaded the center of the box with explosives. Painted part of a 12' x 12' room in seconds. I emphasize, "part" of a room.
As a friend, I must give you some words of caution, should you try this.
1. First and foremost, don't, I repeat, don't tell Mrs. BY what you are doing. Woman are skeptical of men's ideas by nature. You don't need someone bringing you down...think positive.
2. Make sure Mr's BY is not home, and will be gone for at least 7-8 days. You need time to tidy up a bit afterward.
3. Prior to trying this, you need to understand and accept that having floors and ceilings that are the same color as the walls is, "trendy". Again, don't tell your wife, see #1. When your wife sees what you have done, tell her it's, "shabby Chic" (pronounced sheek). Woman really go for that these days.
4. If you don't like #3, buy stock in a plastic or tarp company. You will need it. With the profits from the stock, it will be like getting paid for painting your own house.
5. It's also shabby chic to paint windows, doors, trim, counter tops, cupboards, furniture and knick knacks the same color as the walls. (see #1)
6. But most important of all, beer goggles make everything look better.
7. If your wife does not drink, then you are going to have to leave her a note explaining the "shabby chic" thing. Wait several days(minimum) for the new "shabby chic" thing to wear on her before returning.
It's a win-win-win-win situation. She gets fresh paint(she wins), you get that new shop(you win), and you get to play with explosives(you win) while getting work done(you win again). You win thrice! If you need a drawing of the "paint box," let me know.
