Hi, I'm new to this site and I currently mow 7 yards. I also do hedge trimming, leaf removal and pine needles. I really enjoy it and make pretty good money. I would like to get up to about 12 yards next season. The reason I only want that many is because I'm still in school. My question is how many door hangers should I put out if I want about 6 more yards? What should I expect? I know that word of mouth is a good way, but what other things should I do to get more clients? Also, when do I need a business license? I would really appreciate your help! Thanks!
