For those of you who can get an operator to load up his piece of equipment, transport it to your location, unload it and do an hour of work, then load it up and haul it back again and unload it for a transport fee and and just charge an hour for the work, I envy you.
Around here, they all have a minimum fee of 4 hours. If it's just a small job, they might cut you some slack on that, but they are losing money on small jobs when they can be making a lot more money on the all day jobs. Bills have to be paid, so running around and doing little jobs takes money out of their pocket unless they can charge what they would have made working all day, or at least that part of the day.
As for the hourly rate, if you get a small machine, that the owner doesn't have as large a monthy payment on, and can haul it with a smaller truck and trailer, that also has a smaller payment, then you will save money. Of couse, small equipment isn't as strong as the more expensive stuff, and the bigger you go, the more it will cost you.
For the price of having a piece of equpment come in to move it, you can also just buy a brand new chainsaw. For even less, look into renting a chainsaw to cut it up into smaller pieces.
