I generally take the cost of all materials and double it meaning to plant 1 bush that cost $20 it will cost $40 total. Now if it is a larger job I double it then add some kind of delivery charge and if I have helpers I add there wage in there also plus a little to boot.
2) Labour - I usually figure out how long it will take us and give a figure to do the actual work - generally I keep the hourly rate per person and time to myself. Build in a little buffer time for overrun on time. You do have to be fair, though!
Might look like $325.00 for Labour. Price it to make good money!
The old saying.."If you are getting too much work your prices are too low and if you aren't getting enough work, your prices may be too high"!
3) Pick Up and Delivery Charge
4) Disposal Fee (if necessary - disposing of older materials)
