How to find investors for a vending machine business idea

I have a unique vending machine business idea. I am quite confident that it will work and get popular. But, I still need to figure out regulations, pricing and profitability. Keeping that aside, getting these vending machines will be costly. I don't have any capital to get them. What is the best way to find funding for my idea? The business model will require setting up kiosks at apartment complexes. Location is Florida, US. Thank you for your input.
