I'm not sure how big your house is but the sprayer you use on your airplanes and the one you use on your house are two entirely different beasts. The latex we use on our planes is a whole lot thinner than you spray on the house. Unless you are just touching up the eaves or window frames you will want one of the "big enough to dunk the pickup in a five gallon bucket" airless sprayers. You should be able to get one at the local Rent-All but even if you buy one, you can manage a pretty significant savings over having someone do it. I wouldn't wish brush painting a house on anyone. You may be able to find a sprayer at a pawn shop but make certain it was cleaned. A good quality sprayer can be disassembled and rebuilt. I have scraped down and painted a two story craftsman style house so I can speak from experience.
