Find an angel.  Rich people are sometimes looking for ideas to support.  Some rich people complain that they are inundated with "get rich quick schemes", so choose someone who is open to new ideas.  Investors will usually advertise their interests.  Ask around.  You might find someone willing to invest in your business for a percentage of your profits, if you have a good reputation.  Even if your idea is perfect, you need to have proven that you are reliable before people will invest in you.  A bad credit rating can destroy this for you, no matter how reliable and honest you are.
