Most people provide recent paystubs and/or a letter from their company HR department verifying their current employment and monthly take home pay.

I normally quote people based on what credit score they expect to have and send a fee sheet breakdown.

Bob Marley once said, "You can fool some people some time, but you can't fool all of the people all the time."

Also I hear how people can hire their kids and pay them to do tasks without going the W2 route if you pay them less than 13,500k per year.Is this true and how to do people usually pay them straight from the corp to their bank account?

People are strange. 

If you haven't put the best possible,  experienced people around you, I might suggest getting involved with your local real estate investment groups...many of these people will have experience and contacts that could help walk you through the steps required to make this project safe and profitable or to show you why it might be something to walk away from. 

I will gladly take any suggestions like meet ups, learning websites, books, podcasts, or even meet with other people who started real-estate investing to talk while I buy them coffee or dinner. 

I know many people that would laugh at such a request.

It has been suggested to call these people 1hr prior to the showing time to verify they still plan to come.

It'd be great to have some people physically around me to keep me accountable.
