This is my Roland DG name badge. It took less than 5 minutes to make and cost less than $1. You could sell one like it for around $6. You probably couldn’t sell this one for $6, since I have an unusual name, and anyone with my name is unlikely to have my title as well, which limits the audience substantially. On the other hand, actually making name tags for people with their names on them can be a very good business. All kinds of companies use name badges, and some of them are probably your customers already.
