Something that many enterers into our industry don't understand is that tree work is not about the choice of gear alone. You have to be able to maintain and adjust the gear as needed whether it's a flipline or a chainsaw, or some part of your truck. You'd best be a fix-it guy because things break and wear out regularly.
You need to be a problem solver because climbing and rigging are just a series of problems being solved one after another, not that they're problems, per se, but they're points in time where critical decisions need to be made, and if not made correctly, death or destruction may ensue. if you're not a decent problem solver, I would dissuade you from coming in.
There's customer organization, phone lists, record keeping, contact tracking. Then there's the business name register, bank account for the business, and business cards. Just the bare essentials.
Then there's the working with the clients, which can make you or break you. You're not working with trees until you work with the people. Treework is 90% psychology, 10% treework.
Insurance. Must have it. taxes. Must pay them.
Then there's the choosing of the equipment you will use to start out, and I personally recommend safety gear before a harness and rope. Don't do tree work without PPE. Period.
Lastly after these basic fundamentals are covered, your education begins. Now you can climb trees and become a tree climber.
If you're gonna enter our industry and be a hack, don't bother. If you wanna buy gear to do this one job, then good luck with that. Let us know how you did. That's how a lot of us got started. All the other parts we figured out along the way. We're giving you an awareness of those other parts on a silver platter, spending time with you to see that you understand what a startup tree service looks like.
Does this still look like we're rolling you around on the barbecue, or are we sharing our time and offering valuable knowledge? Your perception is your choice.
