I live in Houston and work nights. I'm broke so I figured I'd give the lawn thing a try for extra money. I have some basic questions, all of which you guys will probably think are stupid, but here they are: 1. When's the best time to throw out some door flyers? 2. I don't want to buy commercial equipment, just a couple of 21"ers. Should I go with self propell or push mowers? I'm in good shape, and I know push mowers are cheaper and have less parts to go bad. Plus, couldn't I get my mowing done faster with a push mower? 3. Which 21" mowers would you guys recommend? 4. For the one-man residential mowers, how much are you guys making a year (net?). 5. Can I get/ keep customers if i just want to do their yards (i don't want to mess with flowerbeds/trees/etc.)? 6. How many of you guys claim your income and how do you get licensed? 7. how many of you guys are powerwashing too and is that worth the time? I'll keep it at that and post the rest of my questions later.
