🦊 If I use my fox base app recipe to craft someone the app, what's a fair fee for crafting service?

30 minutes before the New Year, I defeated a fox and got the base app recipe! 🎆

While I work on collecting all the ingredients myself (I've got like 5 buried RIP) ~ in the meantime I figure I can help someone out who has the ingredients, but no recipe!

 If I use my fox base app recipe to craft the app for someone else, what is a fair price to ask?

I'm hoping to earn some GC to help get my own ingredients or extra ingredients they have left over maybe? Of course this is also a process with a lot of trust involved so should I offer my firstborn son / favorite wolf as collateral or something lol?!

As someone who has yet to obtain a fox base recipe, I've been looking into finding someone offering this kind of service while I'm collecting the ingredients. I would be willing to pay around 20 GC plus refunded slots to the stud receiving the base app.
