Ideas for retail stores

My archeologist family, which has like 4 archeologists, runs a shop that sells artifacts. I am using a mod that makes archeology activities available for club activities. The shop has multiple archaeology workbenches for club gathering where they uncover artifacts and sell them right away. I never restock items because my family is saving up for a new mansion plus some items found in the Selvadorada temple are extremely expensive, e.g. the golden plate and golden frog. My retail shop is pretty big, so I have bedrooms, bathrooms and a kitchen in the shop. This allows my sims to live there.
