Doing a 2 week job with a helper at a church installing wiring for a projector and a programmable lighting system etc. Hard to estimate the whole job so will probably charge T&M (time & materials). I usually charge $45 an hour for me and $20 an hour for my helper. Does $45 per hour sound about right?, or should I charge less for bigger jobs? Or is there a better way to estimate this?
Thanks for any input,
