Thats a nice pile, how much do 5 gallon buckets of it sell for
.
One thing to consider when working for yourself is the liability/risk, jobs that anyone with a chainsaw can do will typically be much cheaper per hr, much like splitting. If no-one else will touch it, why not, usually means they don't feel confident in their abilities to do it safely or they don't have the proper equipment, if you do then there should be a bit of a premium charged for those jobs.
I usually charge 500 a day per machine/man hr, and more if I have to rent the equipment, obviously if you're hiring a crane, then you should be getting enough to pay for that and you should be making money for the crane being there. My close rate is about 60-70%, much of the work I don't get I didn't want in the first place; then there are the clients I tell that another company can probably do it cheaper because they won't be renting the equipment to do the job, and they say "okay, when can you start", theres a reason I'm there in the first place (references).
While these are all important to consider, as has been said, it doesn't matter how much you think your time or equipment is worth an hr if people can't or won't pay for it. Many companies have been started because there was a high demand and they saw an opportunity to make a bunch of money even while charging reasonable prices, but they must make enough to continue to make enough to pay for their equipment/people/other cost, or why are you doing it.
I will say that I charge enough that I can also afford to help others out, if I'm not making enough to pay our bills and to help others, I see no worth in working.
