But not sure how without official invoices.If you are incorporated or an LLC, then there is a way to actually hire your kids and save on the taxes. 

I would be happy to walk you through the rules and regulations of each of the incorporated and unincorporated areas of SLO County.

@Gregory - I also use a GC but I also incorporate hiring subs too so I guess you can say I do both.

The Articles of Incorporation are the most important part of the LLC...

Next, contact R.E.A.s that specialize in corporates.

"I" myself am incorporated in NC as an LLC properies management.

-Incorporate the principles from 4 books into my script: Influence, Pitch Anything, Start With No, and How to Win Friends/Influence People...

For example if you open a LLC in Nevada but your business if located in Colorado then Colorado will have you "re-register"  as whats called a foreign corporation (a company that was not originally incorporated in Colorado) "foreign corporation" or LLC will subject you to all the same taxes and fees as an in-state company.

The terms are not comprehensive and we expect that additional terms [including reasonable warranties and representation,] will be incorporated into a formal agreement (the “Agreement”) to be negotiated.

Make some money in it first, see if it is what you want to do rather than spending money on incorporating first.
