Still looking for VAs? I'm a fully remote voice actor with a broadcast-quality home studio who has 15+ years of experience in the field and several Itch.io games under her belt already! Take a listen to my demos on my website and see if one of my voices is what you're looking for:

As for audio effects, I'm not an expert audio engineer, but I know some other people who are! Let me know if you'd be interested in their services as well.
