Advice on selling cards at my local meetup? I would be the only YGO vendor

Once a month, trading card vendors set up at the mall near me. No one sells ygo cards, unfortunately. 90% is pokemon. I was thinking of setting up a table, not necessarily to profit but to potentially meet others who are interested in ygo. I envision having a welcome sign with Pot of Greed, Blue-eyes, and other popular monsters on it. A duel mat in case anyone wants to play. A couple binders with affordable but valuable cards. Then some boxes to sell in bulk. Is this a bad idea? Any advice is appreciated!
