If I know what the 'true' value is yet there is no one who wants to buy my token, there is no liquidity.Maybe, just maybe, more data about the materials, the performance over time and similar history, will have economic value.

Write down your costs associated with this learning experience and decide if it's worth it to retain an attorney ($5,000+) and pay their hourly fee ($150+) to go after someone who seems like a deadbeat anyway. 

-PASSIVE INCOME: income that would continue to generate if you died; includes rental income, royalties, and income from businesses, investment partnerships, and LLCs where you do not materially participate; not subject to self employment tax but may be subject to net investment income (NII) medicare tax; Can label yourself as a real estate professional to allow passive losses to be deducted and to avoid NII tax on rental income; If you write a book and receive royalties, that income is passive and not subject to self-employment tax; But if you write several books and consider yourself a writer, then you are materially participating and that income is earned income and subject to self employment tax; The IRS does not allow you to use passive losses to offset your active or portfolio income.

Materials are not that expense (drywall, compound, paint, etc.), but labor may be. 

They cover the good and the bad of the business, supply you with a lot of take home study material/reference, and a zip drive containing all of the forms, contracts and letters they use to run their parks.

Your cost should be less than $200/window in materials plus a few hours' labor per window.3.

It's basically the same older material because things like updated laws would not change it. 

Only way to accomplish that is to pay your relative way below what property is worth, or do all the construction work yourself and steal the materials!

I hope to start using some of the material I've picked up here as well as meeting people in the area.

What is it that you would like the individual/individuals to do: pay the workers, pay for materials, pay mortgage.
