I'm putting in a word here for another bidder, Rouan Lucas V (rvanryn). Although he appears as a new freelancer, he has, in fact, contributed to about 10 different projects via my Freelancer account, before setting up his own account. These projects have ranged from linguistics (his specialty) to copy editing. Your project, being a penguin voice, comes within his skill set, as he has both language and technology understanding.
Rouan's relevant qualifications and experience include his double major in linguistics and media studies in his BA and his Postgraduate Diploma in Science (Speech Science). Furthermore, he has attended a course in improvised theater and has had a role as a voice actor. His bid includes a link to a recording of his voice saying your audition line.
