There are several viable business ideas for a 17 year old girl. One option is photography, which can offer opportunities for visual artists and outgoing entrepreneurs. The average annual revenue for a photography business is around $50,000 with a profit margin of 73%. However, it can take up to 16 months to generate revenue and the market growth rate is 0.3%.
Another option is DJing, which can be a good small business idea for teens who have a broad knowledge of music and enjoy getting a crowd going. This can be scaled up later if the business is successful. A car washing business is also a simple option that only requires a bucket, soft sponge, window cleaner, and elbow grease. This can be a great weekend job for teens. Additionally, offering babysitting services or tutoring younger kids is a tried-and-true business idea for teens.
