I offer you a business plan to earn money.
It is a very simple method. But it works.
At first you have to buy many nice, bright and extraordinary balloons. Then inflate balloons and find crowded public places.. theaters, cinemas, the center of your town, kindergartens etc. And I offer you to sell balloons there. There are many adult people and especially children who would like to get nice colorful balloons. You can also make bunches of balloons.
Many people want to have nice balloons at their home. But some of them feel embarrassed walking with balloons down the street. I offer you to wrap balloons or bunch of balloons.
Believe me, it is a great deal!
