I find its not practical to build fences any more, most fence companies do it faster and cheaper here on long island,they get the lumber much cheaper ,they order tractor trailer loads at a time and there set up to assemble it much quicker.in the end there is not much profit in it for us ,so why bother.we base our prices on a per post basis (chain link,wood,and pvc).per custom cuts fee $20,00,hard surface hole fee$20.00,any obstructions in the ground fee (Depends what it is),clearing the line fee $3,00 per ft,take down and cart away fee $ $1,50 per ft take down, $1,50 per ft to cart away the fence,and of course lunch fee at least $20,00,its an easy system, no guess work its all in black and white,what type of fence did you plan on building and why not purchase it?Wood post installation is $35.00 per,that includes nailing one section up,we don't cement wood in,if customer insist the'll be an additional charge,we find the post last longer
