How to turn iPhone repair into a business?

Hello I'm 14 years old and I repair iPhones iPods and iPads and do a very good job at it, so far I have just been fixing my friends devices and friends of friends, But me and my friend would like to start a business, make a website and start fixing devices on a regular basis, we're going to spend some money to make a website and maybe a Facebook page. Any ideas on how to make this more popular?
