Estimating Labor to build drywall

[baruchiz]

It is easy to estimate materials, but what stndards do I use for labor to build drywalls

If you know or can estimate how long it should take.. you can multiply that by the national average of 16.21 for hanging drywall and 18.75 for tape and finish. You probably have different wages than that so multiply it by whatever wages you are paying your workforce or yourself.
Not sure if you're a contractor (I'm assuming you are), but you will also want to put a percentage markup for profit and overhead to keep your business in business.
