For most solo or small to medium sized operations, there is really no need to buy. Sell the stuff first, explaining all the benefits and such. Then, when you have all of them sold that you think you're going to, rent your aerator, and line up a day (or two) and do them all at once. Many rental places are not open on Sundays, and sometimes you can rent it for a Saturday, and not have to have it back by Monday morning. Now, the advantage to this is not just having two days to do them, but more imPORTantly, is exposure. Get out there on a Saturday morning and afternoon when Mr. Johnson sees you doing Mr. Smith's yard, and wants a price because if Mr. Smith's yard is good enough to get it, then by golly, so is Mr. Johnson's. Before you know it, Mr. Miller will be driving by or standing in his driveway from across the street, too.
