I ran out of ideas for my business

I own a rundown supermarket that sells Asian food products, health food, herbal, arts and paintings. My store locates at the center of Oklahoma City Uptown District. Every buildings around mine are developing and businesses are booming with stores that include cake, bagel, pizzas, bars, coffee shops, taco, restaurants, clothing, arts, tattoos shops, and a theater.

Despite a good location for development of new businesses, I ran out of ideas and investment capital.

Can you guys tell me something in your mind? I am open for every idea and I promise that I will appreciate you and seriously think about whatever you can tell me.:-)
