I'm getting ready to put a house on the market, and after 8 years of living here, the white trim and interior doors all could use a coat of paint to cover the various scuffs and scrapes. I'm sure that the pros don't spend hours laying on the floor, scooting across the floor on their sides, while awkwardly holding a paint brush. I assume they mask and spray.

So...I'm young and enjoy home improvement. I'm sure this won't be anywhere near the last bit of painting I do. Would it be worthwhile to buy an airless sprayer and learn to use it? (I realize I'm talking kilo-bucks, here, for a quality unit - compared to how much I hate painting, I think it might be worthwhile).

Or should I hire it done? Is spraying indoors a non-DIY task?
