Been wanting to create something like that but way too busy. Best I can do is link you with some that sort of works.

CATS blender plugin is essential for beginners so you can start your ports of MMDs asap.
I find this one a compact tutorial to start with. Pause and play as needed.

Then this is actually a bit deep in the OP and placed these before there. I promise I'll update the rentry sometime maybe surely
---------- Avatar 3.0 TUTORIALS ------------
HIGHLY recommend that you first watch Sippbox's 3.0 avatar mini tutorial videos up to his 4th one(included) and go along with them with some dummy avatar example. https://www.youtube.com/watch?v=AxnjgvWyqQI&list=PLt8qiEFqNHFkPqpKLnVRx-G78mGvjPbFt
These videos are very short but very informative and should give you a basic foundation on how 3.0 stuff works. And they're very short too(first 4 videos combined are like just 5 minutes)
