I invested $200 in 3 signs + 1 banner for my trailer advertising for leaf cleanups. They've been up for 3 days, only at my house (so far). Already i've lined up enough work to pay them off several times over. I've acquired 2 new clients for next spring as well. both of which were currently unhappy with their current LCO. They decided they didn't want to give them another red cent, and to try someone new. Next spring i'm hitting hard with the advertising!
