I definitely trust these guys as far as financial maturity.

I'm currently a teacher and after realizing that my 1-2% yearly pay raise will never give me any financial freedom I've finally found the thing I think that ultimately could if gone about the right way. 

Under that structure you would be regulated by the SEC and the whole deal should be structured accordingly.If you are planning on having some level of active involvement in the operations and not completely relying on someone (The GP in this case) to manage your capital with the expectation of future financial return on your invested capital then you can go ahead and just go the "partnership" route.

Financially it is not a stretch for my sis and broinlaw without having my parents contribute. 

For whatever reason, I woke up one day, felt like I could achieve financial independence and create an early retirement.

Problem solved. 

I may be able to get a financial partner for this balance but if I cannot what are your thoughts on using an additional loan?

You’ll need to take the financials and put together an Offering Memordandum to present to investors (usually takes me a few days).  

Regarding damages, if you were able to get some sort of financial judgement, the chances of collecting on it would be close to zero.

Theoretically you holding down two full time jobs solves both of those issues.Good luck to you & I'll see you around the forums.
