Keep it fresh and different. Design it yourself, or ask someone for help. Give customers a good image so that they will buy from you again. Hello, others will also help you promote it. One spread to ten, and ten spread to a hundred. Your business will be good. You must also have a good service attitude, and you must be able to talk (bluff), so that customers will remember you deeply. Your business will naturally improve. You can't lie yet, so your integrity will be high and others will be happy to buy from you.
