How much would this cost to make? neopixel ring

I'm always in a sort of dilemma about to handle the requests here.
I don't do odd jobs for (pocket) money, but I like to help out from time to time to focus the requirements etc., and I take a great interest when the project concerns something that I actually want to do myself at some time. For example, I spent quite a few hours helping some guy from Poland to get his Nixie clocks working via the forum and also PM's.
But also I don't want to interfere too much when a sort of commercial relationship appears to be developing between posters.
I just hope it always remains friendly here.
