For one, I doubt any single lender either has or is willing to lend an amount as large as BTC13,500 (which is over $300,000). For another, you're going to have to provide more than you're offering to potential lenders before they invest (which is really what this probably is). For example: what kind of guarantee do you have that your business will be profitable in six months? Do you have a business plan put together? If not, can you create one that can convince lenders to support your business? If you're secretive about your project, people are not going to risk their money on it.
