My parents are interested in supporting me and they are at a stage where they have a comfortable amount of money, they have excellent credit and they have no plans of taking out a loan in their lifetime. 

Consulting with a real estate attorney or financial advisor experienced in such arrangements might provide valuable insights into making this deal happen smoothly.

I knew there had to be a person or department that was senior enough to be stable and to be able to make decisions that weren't actually to the foreclosure stage.   

But DO NOT hire an employee at your stage of the game. 

I am not at that stage yet to spend $1000 + travel expenses for a seminar/workshop. 

I don't think talking and making them accountable will help in any way at this stage.

Unless it is at rough in stage it will be compromised unless this has no interior walls, what's the rest of the story and why does it need overlayed( which is what you are suggesting) or removal which has issues of its own with load walls unless all interior walls, cabinets etc are gone. sounds like a raw deal with water issues or structural issues?

Assuming your LLCs are a sole proprietorship, the accounts should also be in the name of the LLC not your personal name.As others have said, a series LLC is most likely overkill at this stage of the game. 

Do you arrange accommodations for them?

@Chris Papa, if you're going to be investing with a partner, it's definitely money well spent to hire a good attorney to form your entity and draft your operating agreement or otherwise memorialize the economic arrangement between you and your partner.
