Don't know about you guys, but I don't bid anything without looking at it. Minor points can have major affect on the price. I'd suggest figuring it per diem. Example--I've got myself climbing and 2 grounders. A chipper, box truck/dump trailer..whatever. How much would you charge for an 8-12 hour day with that kind of manpower/equipment? Now multiply by number of days it should take you. Be sure to add some "dammit time" for minor unforeseen hold-ups. Say you need a grand a day for 8 hrs. and the job takes 3 days. The bill's $3k plus a little to cover the gremlins. It's a simplified idea and these are just for example, but I'm sure you get the idea. I also "sell it" as a discount rate to the customer. "If I price this by the individual tree you'd be getting pretty pricey in a hurry. I'll figure it by how much we can accomplish in a day and it will save you some money." If you disclose this to the customer, be sure to be as accurate as you can on your estimates. Finishing too soon or taking a few days longer could present issues for you.
