Hi hi! Are you still looking for voice actors? I'm looking for some experience at the moment, I'm on Discord at ObviouslyMichael#4348 if that's a better place to get in touch. I've got previous experience as a live performer (https://www.facebook.com/mjbcomedy) though I'm moving to online projects (there's a recent thing I did with James Ashby at that Facebook link if you want a listen in on my voice when it's just talking generally.
I've got a Blue Snowball for recording voice, and can provide a range of regional UK accents. Most recently I've used variously Good Natured Farmer, Stammering Posh Guy, Growling Monster, and Valiant Arrogant Knight for a friend's project. I don't have access to the recordings, but would be happy to supply a demo if helpful.
Errrrrm, think that's it. Other than that being British, I can obviously also do Evil-Guy-You-Want-To-Hate-Immediately, too.
