Teen jobs in San Fran?

I just started a business about two months ago selling brand name dog clothing "Eli Elite". I turn 15 this summer and im living in San Fran with my sister and her fionce, minimum wage is fine but I need to make $1,000 by the end of summer 2010. Yes i know 14 is early to make a business but i figure with some clothes I could sell before i go, and the $800 i make during the 2 months I'm there i can make enough money. i need the thousand dollars for a dog clothing company in China. I have to spend AT LEAST 1,000 dollars, or no deal. Anyway does anyone know of any cool teen jobs in san fran i can do?
