I am a 19 year old mowing my way through college. I have decided that I do want to build up my business to the point where when I graduate school, my business will be big enough to support me. Currently I have 18 returning customers from last year( about ten are weekly, the rest I keep an eye on and contact them about every 10 days to see if they want it done). I am looking to add anywhere from five to ten solid accounts this year, maybe even small commercial such as dentist office, doctors offices. I have a $1100 Toro commercial grade walk behind and echo weedeater and edger. The equiptment and start of a customer base is there for me. Also, I live in north texas and charge 25 or 30 per lawn( most 25 s take me about 45-50 minutes and the 30 dollars take around an hour) Am I charging too litte? I want to be able to build up my business, but dont wanna miss out on money by undercharging. Let me know what you guys think...also I'd love any other advice about how to build my business up big.
