hogwartsishome | Possible house points or Diagon Alley shop?

I was not sure as to where to address this issue.

I have taken to making custom ID badges for Hogwarts students.
I can customize depending on their house, facial appearances, school information, and personal information.
You can see examples in my most recent personal journal.
I have already made 5 for my friends and I was wondering if I should inquire into making this a shop in Diagon alley or would this be appropriate as to making graphics which might count for house points.

If this is not allowed, please delete this post, but I just was not sure where to address this.
