It might feel like everyone's become a photographer lately, what with apps like Instagram, but that doesn't mean everyone's good at it. If you're someone who knows how to capture moments according to light and composition, then you'll provide a great service to a friend.
What it takes: Using your own camera (or borrowing one if you don't have one) and snapping pictures either for a friend's big event or for a family portrait. Edit the photos and then give them to her on a CD.
Typical cost: Up to $500 an hour depending on expertise.
