I'm not in that business but I'm thinking of buying a portable gas washer, I guess a pole and a surface cleaner. 3.5 gpm 3600 psi or so. I was wondering if 5000 flyers would generate work? I've never seen Power washing ad before and I'm not sure if they would go in the same neighbourhoods I put window cleaning flyers in (Newer areas with casement windows). Just looking at for some insight in marketing especially since it's going to be slow for the next month and a half.
