To be honest... your best place to start would be to apply to work for a company that fixes up homes to resell. Then, after doing the construction part of the work for a a year or two... try to move up to management.. the entire time socking money away for your own start-up costs down the road. Then, after a year or two in management, and when you think you have enough money squirreled away, and you have enough experience... then go to SCORE, or somewhere else to have them help you write a business plan to take to your bank. Anything less than that and I can't see any bank loaning you money, or anyone with any business sense loaning it to you (again, you said you have no idea what you are doing and no money, which would be a bad investment). A good idea and no idea how to run a business has very little chance to go anywhere but in debt.

Many people complain about "Big Business" and how they are only after the "Profit"... well, that's how they stay in business and hire people.

I am not saying that you can't do it... but you need experience, capital and time. Good luck.
