A way to make customizable items locked behind course completion

Use case/idea explanation: New user goes looking for a wand, but they want a unique wand! Ah, theres one. "Custom Wand", it says! But wait - the purchase button is grayed out. I hover over it, and the tooltip says i must complete the Wandmaking Course before I can purchase this. Huh, well alrighty then. Sometime later, I do so, and thoroughly pleased by my accomplishment, I head straight for the wand shop! As soon as I purchase my wand, it gives me the opportunity to describe and name my wand in any way I choose, making it truly my own! I also know for a fact that this will translate well to other sites. I hail to you from Galaxies, and the origins for this idea was my desire to name my droids and give them a backstory, which at the moment I can only do in my characters BS, but I would love it to be on my droid "Items" as well! I think giving it the addendum that you must complete a course first (like wandmaking, or mechanics and engineering for my droids!), this keeps a balance on just how many people will have them! It will also incentivize/reward course completion.
