Using ICoG from the Attendance event?

So, I've only got 5 of these scrolls, and I was wondering what would be good to use them on. I don't have anything like tyrants, or root abyss gear, or any other high-end stuff like that. I figured I could use a few on the level 150 badge, or some tempest accessories for my personal use. Or I could sell services or stuff. But how does selling services work in that case, and what's a good amount to charge? In Bera, by the way. Thanks everyone!

I also have a similar question for the Unique pot scrolls. I'll have 7, and I plan to at least get a few items to unique, but what would be good to do with the rest of them?
