where to buy 3d model and mocap for a martial arts game?

hello i’m planing of making a martial art game and i’m planing to buy some models and mocap to work with it and use them into the game.

anyone know where to buy 3d models for this kind of game?

p.s.: please models for actual generation of game models, because i know some site to buy models, but low poly and not actual generation of game models.

thanks you in advance for the help.

mixamo for mocaps or animation packs from unreal launcher.
models form epic store or polypixel or turbosquit or envato marketplace.

Cheers!

thanks for the info
