Hi I'm a bachelor of science in audio engineering, a musician, a composer, and a voice-over actor. I've worked on many projects and won a few awards, so I offer all of the audio work as one man as it seems you are looking to outsource a few people there, I have a studio built into my home I have voice-actors on-call I can mix, master and prepare your audio professionally. I even offer 5.1 surround sound, but if its just for YouTube that wouldn't be needed. So I hope to hear from you, I'm a good composer too, I've won awards just for music. I hope you make a smart business choice and hire one man for all audio, save some money! Kind Regards, Paul.
