I came from a forth generation tree care family so getting started up was not an issue for me. Some things I might look at a little differently than others that have started up them selves. As others have said, your work will get you business, don't screw up. I don't know how many times I've heard guys say "I was 99% sure that would have worked, Oh well, accidents happen". The truth be told, most accidents are caused, and they are caused by guys who think they are 99% right, and they are 85% wrong. The only claim we ever had for property damage was caused by me. We had a hornets nest in a Juniper hedge that the homeowners were supposed to have taken care of. They didn't, so I grabbed a pole saw and wrapped a rag around it, a little gas, and no more hornets. The lady didn't tell me they had just stained the Red Wood siding. Poof. My dad always stressed what he called a factor of 3. Almost all accidents have at least 3 points of human failure to take place. This one did, the obvious 1) Me using fire on the end of a pole saw. 2) Not checking what the empty cans behind the bushes were. 3) Not checking to make sure the hose was working. I saw the hose and pointed it out to my groundie, but when he grabbed it, it didn't work. He ran around back and it was 50 ft from the fawcett and not hooked up. If you take any one of the 3 failures out, the accident wouldn't have played out. We had the fire out in a few minutes, but not quick enough to prevent damage. If you screw up like that and don't have insurance (I know you said you're getting it) the other guys in the area will make sure every one knows about it. I like the idea of door hangers, if you are working within a couple houses. I don't like them when you drive around on a rainy day and put one on every door. Cries newbie with no work. Same with posters on phone poles. If someone asked me if I knew the guy on the poster? I'd just say some high school kid with a chainsaw and pickup. Now the door hangers, I like. You can always jot down a short note on it, "I was working two doors down and noticed you had a dead tree in your side yard. While we are in the area we could give you a free estimate and a discounted price." When I say discounted price, I don't mean half price. I mean maybe $10 or $20 in gas money you didn't spend driving out for the estimate. We were well enough established that we charged for estimates for new customers, deducted from bill if we did the job. Weeded out the people who called every number in the book looking for the cheapest price. That's a big one too. The cheapest price. You have to be able to look at a job and know how long it will take to do, and then know how much you have to get to pay the days receipts and make some for you. I wouldn't take a job unless I could make at least $65 per man hours, and I've been retired a long time. Some jobs you will make a lot more, but you have to know the limit that you can't go below. This work is hard enough with out doing it for free. I've rambled enough, good luck, Joe.
