You have to take your pick between charity and business.

One thing in real estate and probably most other businesses is that most people including me don't know how to measure and evaluate risks.  

I bought a business where the prior owner had it in an S-Corp, the S-Corp and he was sued personally for three million.

In my experience, the good ones are expensive, typically require a subscription, and sometimes they even do a physical inspection of your premises to verify it is a legitimate person / business in US.

I know some municipalities allow the property owner to obtain permits but  that in itself is a huge issue in many areas and secondarily insurance is critical in this business.

You can't use a PO Box for a business entity.

I would look up NARPM and start with them..Below are some questions I would think would be a good starting point for you to see who really treats their company like a business or a hobby.

It would be nice if you gave them more than that, because it takes a lot of effort to move a business (online marketing, business cards, etc.).

Any other sympathy is unfortunately just Poor Business Practice.  

Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom.
