My family and I are thinking of going into a new business. Can you give suggestions?

My mom owns a small salon. She's been a beautician for the last 12 years.However, with the constant demands of customers and appointments, my mom has been working non-stop 7 days a week for more than 12 hours a day. I've been telling her to quit and sell the shop and start a new business, doing something that is not so stressful and tiring. Financially, we cannot give up the salon now since its our only means of support, but soon we hope to. Can you help me brainstorm some ideas for a another business venture? thank you
