I want VTuber avatars, but I've run into roadblocks trying to make my own, and I can't afford to commission any. T-T

Hi! We're a fairly diverse plural system with various origins and interests! ADHD, autism, likely BPD. Uhm... Yeah, gonna work on this a bit more soon?
I want VTuber avatars, but I've run into roadblocks trying to make my own, and I can't afford to commission any. T-T
which roadblocks?
it's limited, but vroid+vseeface can be set up in an afternoon
No mouse ears (and efforts to make them through hair manipulation have kept on messing up -- this alone wipes out most of our system members who might want to stream) no calico fur pattern that I managed to find (issue for Rei)... maybe other stuff?
i dunno how to do hair ears but i draw my own skins in vroid, so calico fur patterns are very doable. i have a quick cyborg skin i use.
We aren't good at drawing, so might need someone else to do it, or to find one online somewhere. (And also, no horns, which is rough for Esther or Lily)
