Contractors especially I've found to be very unresponsive & unreliable so I was looking for more of a consistent process in building a successful portfolio that is not creating another 80 hr work week for myself. 

I can't imagine someone at Amazon being able to take on flipping alone though; it's definitely another full-time job, and at times even more taxing than a 60-hour workweek.  

I already work a 80+ work week and study after work.  

Read "The 4 Hour Work Week".

Honestly, I think this feeds to our competitive nature in keeping us motivated to schedule 6-7 day work weeks, even when we are drained!  

I stay in Merced during the work week.

Find out for yourself, but it sounds a lot like a 4 hour workweek "position yourself as the expert" business model, where he sells you on some system that you can easily do yourself.

Although Turnkey doesn't always get the best rep around the REI world, it seems to be a perfect fit for me due to my career demanding 55-60 hour work weeks, so I can't be hands on 24/7.

So, you will need 81-hr work weeks, year-round. 40 hours at your job plus another 41 hours in real estate.Your wife may qualify as a RE Pro if she does not have a regular 40-hr job and spends a lot of time in real estate, minimum 750 hours per year.

I am not saying it isn't possible, but hardly autopilot (despite what the 4 hour work week told you).
