First, why do you want to go to the studio to do this action? Is it too backward to sell jewelry?
The service of the second studio itself is suspected of bundling and secondary sales. Are you sure you want to do something so heavy?
Third, your customers are not all in the photo studio, so consider the gathering place of customers.
Let's go back and solve the trust problem, the cooperation trust problem with the photo studio, and the trust problem of the customers who go to the photo studio. If it is in the form of store association, we will naturally eliminate the trust problem. If it is binding, we should consider which products are more suitable and which user groups to match (such as newcomers who take wedding photos first and then buy jewelry). We can't pack ourselves too much. We should consider packaging the photo studio itself. After all, you have used the means of relying on others to eat. The division of profits should be clear, and the rights and responsibilities should be clear.
