Jake, I thought you already did voice-overs; you're definitely a pro at it. I've hired many voice-over talents for films.
I definitely suggest you get the demo reels out there. Check local actor/voice-over websites and put your stuff up there. The benefit is, since you have your own equipment, you can do business through the web. No one has to bring you into a studio and pay extra studio time costs.
Take it from someone who spent hours look for someone to voice Theodore Roosevelt, and kids saying "Awesome" and "I want one!" in my last film, you're good.
Now go on and get yourself out there!
P.S. Loved the "Lethargic Mexican."
