Unfortunately I don't know anyone who does nendo commissions but I've found that often people who do custom ones themselves buy bootleg nendos that cost around $10-30 ; v ; on Ebay then repaint, edit the parts and what not. It seems better to buy the bootleg ones for editing cause then you're not throwing down a pretty penny on official things which can cost like $35+
Not sure if that's any helpĀ
Sorry if it's not too helpful;;;;;;
