the way your figuring out your hourly rate is not right. You cant say 9$/hr for helpers then $32 for me and my dad. You need to add up your total costs as a whole, multiply it by 4 (weeks/month) then divide it by the number of hours your working (320, 8 guys 40/week) then thats your break even rate. Then multiply that by your profit, and come up with an hourly rate for one person. That hourly rate includes, projected wages for employess, insurance (gl, auto, wc), rent (shop, office: even if your running from home it should be taken into account), cell phones, landlines, repair budget, fuel budget, equipment, tools etc. So if your nut is $15/hr and you want to make 50% profit you would charge $22.50/hr. I would not put down a bid that says $150.00 per hour simply becasue management will see that and fall out of their chair. Even if you put down 8 guys working. That brings me to my next point. If you have 8 guys working, you will be much more profitable and productive if you split things up. You run a crew of 3 and your dad runs a crew of 3. Seperate properties and all. Its been proven time and time again that the less people on a crew the more productive they are. If you have a really big job, then both crews can meet together and start, and get a jump on it then leave and head to the next job. Thats what I would do at least. As far as price thats on you. Nut X Profit=bid. I play around with my profit margins usually. I try to gain anywhere from 30-50% profit on any job. On something like this probably in the range of like 35% or so just because of the volume. I am not trying to sound discouraging, but it does sound like your in a little over your head personally, if your asking for help on this stuff. I know your getting advice but thats just my opinion. I would tread lightly though on it simply becasue it has been changed 3xs in the last 4 years. Lastly, most likely if you do get it from the sounds of it youll have it 1 maybe 2 years and then it will be gone to the next low bidder. First year your set to make 6 digits. Ill go on the generous side and say 150k for the year, you add in that 300k accoutn that puts you up to 500k (figure more work added too) you lose that account in a year or 2 and your down to 200k again thats a 60% loss in your business which could be the end for you.
