Lending to Someone with Nothing

[Chris Hamm]

I've checked out quite a bit on here and my question seems to be only partially answered for my situation. So, here's my question as it fits to me:

I have no backup money; I rent my house; my car isn't paid off yet. As far as personal property goes, I own nothing.
I do own a business, currently undergoing a change from sole proprietorship to LLC so that I can open up a second business under the umbrella for REI, but that's neither here nor there.

My question: where do I even start to find a lender to help me on my first REI? Again, just imagine I have absolutely nothing but time, sweat, and a high level of motivation.
