If you don't know already, I'm new to the business. I just sent out flyers last week and I'm starting to get the calls! I gave out one estimate and I have been asked to give several more. When giving my estimate for mowing, I thought of a question. What should the additional cost be for bagging? My estimate for this lady's lawn was $30. I was thinking about adding like 15% of the normal mowing price to get the bagging price. What do you guys do?
