no where in the country can you do 100% of the work. No untily will let you touch thier stuff, some will let lic people do it. for the most part you still need to envole the untilty, to do part of it.
What I'm talking about is if a job cost 5k to do, and they only bill you 1k, some one is still paying for it. Its just not you directly, it does not make it less expesinve.
While some costs can be very diffrent from area to area, many stay the same. a 90k back hoe is a 90k back hoe. 20 gallons of fuel per hour is still 20 gallons of fuel per hour. A truck tire is a truck tire. Etc, etc. The fact of the matter there are really only 2 things that really change price wise in this country, thats labor and material. In the case of road way construction, the main reason why materail prices are diffrent is do to transpertion cost. if you nee 3/4 crushed stone and you live in say mississippi, you are going to pay more for it then you would here. Sand would be the other way around.
