Like it says on the tin, I'm willing to go in and convert whatever digitigrade avatars you may have to have properly articulating legs.
If you would rather do the leg work yourself for free, the tutorial can be found here. (Pun 100% intended.)
I apologize for the price increase, but there's been so much interest in getting this done by me I needed to slow things down. May have to keep going if this doesn't do anything.
(The prices had been reset back down for some time now, guess I forgot to fix the description, oops.)

List of avatar bases that have been converted:
Hyenid v1.11
Nardoragon v1.1 (Base)
Mewlin 2019
Flute Avali v1.1
zDragon v7
Rexouium V1.1 OptFox3 VRC V258 (Thanks CaseyFemFox)
BestBoi
Kita'vali v4.8

Note about converted avatars: Due to the nature of the conversion, the skeleton and likely mesh of the avatar have been significantly modified from the original base enough that you will basically be guaranteed to have to also convert any accessories meant for that avatar that go over the legs in any fashion.

Also a note about Base mesh conversions: While I still am willing to do them when inquired about, due to the sudden surge in interest and attention digitigrade in this fashion has had, it may be worth asking avatar creators with bases about doing official digitigrade conversions of their models before inquiring me about it. I don't want to do a conversion for someone, then come to find out 2 days later the 'real' version is officially converted by the original creator, wasting the commissioners money and the effort put forth to convert it.
