I would strongly suggest you should do a budget for your year with sales / variable expenses / fixed expenses. This budget is going to tell you what amount of revenue you are going to do and the most important thing, what margin you are going to do that revenue at.
So if you did a budget at a 50% gross margin you need to be sending your quotes out at a 50-55% margin just for some slippage.
If you're J man cost you $50 / hour + say another $10 for the insurance / other stuff he cost's you $60 / hour at a %50 gross margin you need to charge $120 / hour for him. And if your materials are $500 then your charging $1000.
Worry about your margins and what you need to charge and don't worry too much about the competition. You know your numbers you don't know theirs and their overhead.
Quote each job at a flat rate at the margin you need to hit.
I don't like hourly, I find it dangerous to hit the client with a large number at the end and hope they pay it. I like the upfront price, get a 50% deposit with CC on file and life is great !
