There is a lot of good information posted in this thread. Please take serious. I have been doing this full time for 4 years and I have way over $20,000 worth of equipment.It takes time to build a good client list. Think about what yards you want to do and the size of equipment that will fit on those properties. Are they flat?Do they have gated back yards?Does your area have a lot of hills? Just to give you a idea of operating costs my fuel bill is over $200 a week.Insurance is almost $2,000 a year.I bought a new mower back in the Spring and it was $6,000.Your cost maybe lower but insurance is a must and if you buy a new commercial machine of a known brand they are $5,000 to $12,000.
