How to estimate lawn mowing & leaf removal jobs?
I love collecting leaves in the fall to compost. I collected about 1000 bags this year and close to 1300 last year. I've mounted a vacuum head on a horse trailer to collect unbagged leaves that people rake into piles in places where they don't have to be bagged.
I've been thinking I could make money from this in my spare time if I collected the leaves for people instead of waiting on them to bag their leaves. Then I'd have clean leaves without so much trash in them. I'd probably focus on larger yards where I could use a mower and a vacuum/shredder/collector and make it worth my while to haul them back home.
So how would someone go about estimating a job? Size, time, arbitrary guesstimate? I know it has to be enough to cover my basic expenses if I used a mower, but not so much that it wouldn't be attractive to potential customers.
