What to sell for shops in Stanley Market?

We run a shop in Stanley Market. Every day lots of people pass by our shop. It has too many people walk by and no time for them to shop during the weekend because it is too crowded. Also, the opening hours of most of the shops are 10-6pm. What should we sell to have the best benefits? We tried painting and artwork. There are many people go dating in Stanley. What service we can provide to dating people? I bet on Feb 14 will be the worst business day again.
