Although AB-968 doesn’t specifically mention “licensed” contractors, the state of California already stipulates that “anyone who contracts to perform work that is valued at $500 or more in combined labor and materials costs must hold a current, valid license from CSLB” (source: CSLB).With AB-968, if work is performed by an (un)licensed contractor in an amount that exceeds $500, disclosing that entity’s or individual’s name and contact information becomes a legal requirement.

Labor costs for skilled labor vary across the country as well as with the age of properties so I think you would want very local data to use. 

Especially since you have so much help.A rented sander and supplies will cost you about $300... all the rest is labor.

@Joe Fairless This is an email that I sent to Seth Williams after we sold our first property.  

So I the owner am having to paint a large portion of house.My question is, can I deduct a calculated amount based on my time and work to do this labor?

I can tell you right now the cost for sheetrock, labor to install, mud and tape and sand to level 5, prime and 2 coats of paint (7 different colors throughout house), touchups were about the same as what you seem to have been charged. 

Some companies give a "Full Transferable Warranty" but then hammer your with fees on labor or some other way to get more $4. pic below is of the severe fdn. settling in the kitchen.   5.
