So I'm new to the wholesale market, I'm slowly getting the hang of how to go about getting leads on houses for sale and generally on selling over to the companies, can anyone help explain more of the legal side (contracts with home owners/contracts with buyers)Thank you for your time

You can do it but properly doing it tends to cost a lot on legal fees to do it properly to protect both parties.

Banks also tell me I'd be a bad investment if I were to get a non-legal job in Florida to supplement my income while growing my new firm, since I'd be working far beneath my education level. 

I’m hoping the landlord will allow us to just pay for the next month while we wait on closing and moving our equipment and inventory over, but I’m curious what they can legally do to make us vacate should they become unhappy with the situation. 

Do not rely on it for legal advice.

Or could they be bending the rules and putting in contracts on properties that they probably don't even know what it looks like; is that even allowed/ethical/legal?

As Jacob said, I would just have her sublease if your lease doesn't restrict her from doing so. 

Do not rely on it for legal advice.

It's always prudent to to consider the cost benefit analysis of pursuing any legal action.
