Consult a CPA.

First of two steps is to consult the State License Website www.myfloridalicense.com for education and other requirements .

Your best bet is to consult a structural engineer.In Georgia, we'd just header the wall off.

I would recommend if you could find a really great attorney/accountant over there that specializes in these sort of legal structures to get a consultation to find out what your best options are and to protect yourself and your investments.

I only invest part time- and rely on my career as a CPA/anti-money laundering consultant for my living expenses.

I am not a tax consultant.

There are many valuable aspects I learned as well, like consulting principles,  negotiating,  teamwork, and time management.However,  if you are a budding entrepreneur and need specific skills, I don't know if spending so much time in an entire MBA program is best for your growing business.  

I am an Energy Efficiency and Renewable Systems Consultant.

You will just be an Independent Contractor / Marketing Consultant.)3) Ask Them How They Want To See The Leads Presented To ThemKeep this simple.  

You should probably either do more research for your state laws regarding a garage/residential storage area or consult an attorney.
