I agree that your price was low. You don't want to bust your butt and only profit $100 bucks at the end of the job. Your not making any money that way. Price your jobs to where you make a good profit. Don't go crazy when factoring in profit, but don't just do the job so you can say you did it.
Also, just because the company you work for now charges 34/man hour, doesn't mean that is what you should charge. Everyone has different overhead that they should factor into their hourly rate. Make sure your covering all your costs. We have our labor costs broken down to the minute for each crew. Just some food for thought so you're better prepared next time. Good luck with the job!
