9 years ago, when i was 19 i had a 3/4 ton pickup, bought a husky chainsaw with a 24" bar, and a used stump grinder. i started doing stumps, and the occasional tree job. then as i got bigger tree jobs, i would hire to have someone help me with the cleanup, other friends with dump trucks etc.
then i bought a dump trailer, so i could clean up bigger jobs on my own, and a 1-ton pickup.
i could always hire a bucket or climber if i couldnt take it down myself.
if the job was too big, i turned it down.
i started getting alot of bigger jobs.
then i bought a new stumper.
then a tractor, and bigger dump trailer. now i just bought a clam truck.
i didnt take it seriously when i was 19-22. but when i bought my house at 23/24, i really started taking work seriously
word of mouth and internet will be your best advertising- phone book is a waste of money.
also, at the end of the season i send out post cards to customers saying thanks for their business. that way, they are reminded of me and the trees in their yard, and if they lost my business card, now they have my # again.
when you clean up after jobs- make sure the yard looks better than it did before you got there. you can do the most dangerous job in the world, but if you leave a mess, they'll remember you as the company that left a mess, not the company who did a tough job safely. i have a bunch of reviews placed by customers on my business, and they comment on how clean the yard was when we were done, and how fast i returned their calls and scheduled the job. i often get told i was the first to return the phone call, and the people appreciate that.
