I've decided to start doing lawns this coming year. I plan to put out door hangers for a good 100 hours in mid-February. Besides basic mowing, what else do I need to know how to do for an average account? I'm not very knowlegeable about lawncare. Where do I find out how to do these extra things (if any)? I need some extra money and figured I can make more doing lawns than at a dayjob. Two other questions I have are what do ya'll put in your "contracts" and how do I get licensed/what does the license cost (I'm in Texas)? Please pardon my rookiness.
