Dot if you decide that getting it made commercially costs too much and it needs to be homemade:

I have an English friend who does a lot of baking but is asleep right now, I'll ask her tomorrow about it and see if she thinks noobs like us/myself are capable of making it.

Looking at the pic it looks pretty simple but time consuming - the cupcake themselves should be really easy and the topping should be easy to make, the writing should be easy and the only hard part should be the nexus and the minerals/gas because they take crafting skills but it should be fairly easy to make a block of sponge that someone with skills could craft if anyone could do that? (zepph?)

Could get some people to come bake at my house all day on Friday.

^ A last resort anyway
