Thank you Lucy, if you'd posted that initially you'd have got a completely different reception.
A trawl through the forums will show that we get at least one "wanted, someone to work for nothing" post per week. Nearly all of them are for commercial jobs. A lot of people claim all sorts of things to get people to reply. there's no way we, in your initial post, could tell that you weren't yet another firm looking for mugs to work for free.
So now that you've taken the time to tell us who you are, what you're doing and why you're not in a position to pay a wage....
Welcome and I hope that you find what you're looking for.
Edit: I've got to agree with Nikosony about the miming, didn't work for me I'm afraid, but I like the sounds, and now that you've shown yourself

hopefully you'll find some video-makers to help you out.
