Hi Luci,
I see you haven't really gotten a response here. As you noted, Mysidia Forums are pretty inactive. I think you'd have a better chance posting on a subreddit like r/inat or r/gamedevclassifieds. You can also try TGL.
Just know that what you're looking for here requires some time. There's a 99% chance people aren't going to just work for you for free or trade their time for your art that they may not need, and I say this in the nicest way possible.
Some of what you are looking for can be found as mods posted in these forums. You'll need to be willing to dabble in the code a bit, but it's not too hard once you get the hang of it. I started out as a complete newbie here and quickly learned how to tweak and add things to the framework after some time. The adoptable descriptions/profile is something Kyttias created which
you can find here. Based off this, I created
Species Rarity with Images and
Held Companions and Items. If you look around at some older threads, you can find more as well.
Hope this helps!
