I got my a grade licence a few months ago, so I'm sorta new to giving quotes and stuff. A 'good' friend of mines dad(step-dad) installs motorised roller shutters(labourer, not an electrician) for a living and asked me(through my friend) if i could wire up motorised roller shutters for him. $60 each shutter. He didn't ask me how much I'd charge him, he offered to pay me $60(invoice, GST, etc) a shutter. LOL. So, i've been doing cashies and i charge $100 CASH(no paperwork) to install a powerpoint(supply and install), so it's pretty suss because it would literally take the same amount to wire up a shutter and i'd be charging i guess 20% more. Now this labourer(certified peasant), don't tell him that, thinks he can offer me $60 to do that. Anyways, so he is going to install the shutter and motor. I have to run/install/provide cable, junction box, switch next to the window, in other words supply power for the motor and install a switch. I haven't replied yet and just want some some numbers from you guys. How much should i charge my lovely friends step-dad? I was thinking $120-$150 range. Thank you in advance.
