Affiliate Marketing Secrets

Hello. I am 15 and I want to start my own online company. I don’t want to do affiliate marketing, MLM, etc. I want to actually start a company that sells a product or service. But since I don’t have a product, I would like to sell a service. What kind of service could I sell? I thought of a online music distribution service company that would put other people’s music on iTunes. The problem is, people can do that through Tunecore.
I also found a free website script on the internet that creates a music sharing website where bands and artists can share their music, and listeners can listen, rate, chat, etc.
I would like to make real adult money (50k-100k a year) from my company. What online service company could I start? Any ideas? I can make a basic website on webs.com, so would small businesses pay me to create a website for them? Any other service company ideas that could be very profitable?
Thanks.
