I started my own lawn mowing business when I was 12. I was doing pretty much anything anyone wanted as long as they paid me cash. Make flyers and market yourself! You'll do just fine. (I had all the toys I wanted). Luckily, I took some of the money and invested it in mutual funds. It kept growing and is still growing 15 years later. Now it makes me money for NO WORK :)
I don't think their is an abundant amount of jobs for a thirteen year old but if you are craving for a duty/job,try cleaning people's car like at a car wash or a local car cleaning business
at 13 you can:
work in a business that is OWNED or operated by your PARENTS,
work as an actor/tress in TV, theater, Radio, or movies,
work as a caddy at a PUBLIC golf course,
work as a referee/umpire in a MUNICIPAL sports league,
or work picking and selling of fruits/vegetables on a PRIVATE farm
you always have the options of casual labor (working in a home) such as:
baby-sitting
pet-sitting
house cleaning
yard work
running errands
tutoring
in every state in the US under FLSA (federal labor law) which most states use as a guide for their own state laws; a minor 14 or older may work in an:
Office,
Grocery store,
Retail store,
Restaurant,
Movie Theater,
Baseball Park,
Amusement park, or
Gasoline service station
Businesses such as Publix, Kroger's, Food Lion, Sonic, Chic-Fill-A, McDonald's, Winn-Dixie, Krystal's, Dairy Queen, and Burger King along with smaller local businesses that are in the same genre tend to hire those your age.
Fast-food and grocery stores are willing and able to train new employees but........................
Minors tend to have many issues that affect their ability to work such as tardiness, absenteeism, numerous schedule requests, poor work-ethic etcetera.
I am NOT implying you will have those issues but the fact that many your age do makes it more difficult for you to get an opportunity to prove your worth.
Because of this you must be able to show through words and actions that you are reliable, dependable, punctual, detail oriented, coach-able, mature, and team oriented.
You will also need great references since you don't have work experience. Talk to teachers, counselors, clergy, coaches, club sponsors, and directors of places you have volunteered or people you have done casual labor for and ask them about giving you a reference. Get accurate, current contact information for them and ask them to be ready to get calls for references from potential employers.
Remember:
Most businesses are individually owned and operated so it is the owner’s policy and past experience with minors that will determine if they will hire you. Apply everywhere you can, the worse that can happen is they don't hire you.

Mowing peoples yards and doing extra chores. But other than that, there isn't a real job some one your age can get. Good luck though (:
