Biggest problem down here at present is everyone is chasing work, and alot of people who owe money on machines are cutting prices just to keep going, and hope they can recover next summer. Me i always said i can go broke in the pub, and still have a good machine to sell, ie i don,t work for practise. or nothing.
Other problem here is any idiot can hire machines from porter hire and try there hand at eartmoving. This alone has killed alot of the hourly rate jobs in my area for alot of us one man band contractors; diggers and/or dozers.
Only way any of us are surviving is with contracts, you price a job to best of your ability and go from there. Again i would rather lose a job on a good price, than get it for a ridiculous price.
Couple of other things if your going to be a owner operator; you better be good at mainentce, repairs, welding etc. Plus be your own sorta surveyor, estimator, accountant, banker, and gun operator all rolled into one.
Think your well out with the fuel cost. I need 30% for fuel. But you will get away with less for diggers, esp small ones.
Hourly rates seem to vary with areas, some are good and some are pitifull. One guy who cuts rates kills it for everyone. At least down your way in the pumice you can work in the wet, up here in the clay, all we do is make a mess.
Lastly inmho you don,t want to owe alot of money on gear. Although if you get a contract you have to have good gear too.
Come back with some more plans if you want some more info.
Lastly for our population, is one hell of alot of diggers and trucks out there !
Cheers Merv
