ISO of a custom made thing Spire related

Title is relatively self-explanatory, but to elaborate: I have several band flags hung up on my walls (26"x41" I believe - I will have to measure one for myself when I come back home from work tomorrow since my tape measures are at work (I work as a blue collar worker)) and am genuinely curious if anyone knows of someone capable of creating their own flag?

I'm more than willing to commission it, but my endgoal would be to get 5 flags. One for each character, decorated and themed around each character, and then a fifth one with the Spire in the background and all four characters around it.

Already checked out Etsy's "Slay the Spire" search and none of it fits my desire, so I'm reaching out to the internet to see if there's somewhere I'm missing, or if there's a connection to be made for said interest.

Thanks in advance! And good luck on your Spire quests, whether they be newly started A0-A10 runs or A20H run after run after run!
