Looking for a nice rig to beef up my animation portfolio

I’m looking to get some variety in my animation reel, which if you’re curious you can see here: https://youtu.be/sjJVsLO7Seg

I’d like to be able to work ideally with a female character with some weapons and a nice facial rig, but I’m open to anything. I love making expressive cute characters, so my work is lacking right now in the “serious” department. Have a rig you’d be willing to share, please send them my way! Have suggestions or affordable options? I’d love those recommendations too.
