So far some of the advice I've seen is spot on, some is not. 50 lawns/week, small lots 1/8-1/4 acre would be a cakewalk, assuming you know what you are doing and have the right equipment. Most of my lawns are on 1/4-1/2 acre lots, take out the house, drive, beds, etc, and my average lawn size is about 6,500 sq '. I can do 20 of these lawns in a day using a 36" walk behind with a sulky. Here are the problems with your original post, from my experience. 1- A 30 mile radius is too big. No one pays you for sitting behind a windshield. Gas, and other vehicle costs would eat you up. 2- In my area at least, there is no way you will average $35-45 for lawns that small. I average about $30/lawn, and I charge more than 80% of my competitors. 3- If you are just looking at business ideas, and don't have experience mowing, look elsewhere. Mowing has a low profit margin compared to other service based industries. It is much harder to make a decent profit mowing than it is to scoop dog poop. It is labor intensive and requires good commercial equipment. Case in point- While I was out doing some fertilizing work. I happened to see a mowing crew pull up to a home. I fertilize this lawn, and happen to know how much they pay for mowing, $27. Three guys get out, drop the tailgate on a 16' trailer with $12-15K in equipment and go to work mowing, trimming and edging. While they are working, a guy pulls up at another fert client's home. Just one guy in a well marked small pick up. Grabs a bucket and a little shovel contraption, and goes to work picking up the dog poop. He is gone and off to the next job in less than 5 minutes, while the mowing crew is perhaps half way done. The house he'd just pulled away from was my next stop, so I asked the homeowner how much he paid for the service. $10/week per dog, 2 dogs, so $20. This guy finished another job just up the street before the mowing crew finished. Soooo, the mowing crew (3 guys, big truck, $12-15k in equipment) gross $27, in the same time that the poop-scoop guy grosses $40 with a compact truck, a $20 scooper and a Home depot bucket. Seriously though. I am pretty fast at mowing and trimming. I work quickly and try to be very efficient, tight routes etc. My best mowing days, I gross about $600. If I am doing spray/fert work, I can gross that in 3 hrs. When all is said and done, I net about double doing fert/spray work as I do mowing.
