Acapella music for Animation Opening Sequence

I need a music composer who can create music using only vocals, mouth sounds and editing software (no musical instruments) to create a track out of an already written melody. The purpose of this track would be used for my animation/content creation brand and this particular piece would be tied to an animated opening sequence for a live stream. The vocals will have to be male only (strange, I know, but there's a reason for it) and the style/genre of the piece would resemble some of these tracks:

“Carry You” - Novo Amor

“Colourway” - Novo Amor

“Intro Song” - Swiss Army Man Soundtrack

The composer will be given a full brief and run down of what we're looking for for this music track once their proposal is accepted. We can say for now that this track is set to be no longer than 50 seconds and we're going for a "dream-like" theme for the piece. Our current deadline for this project is October 30th.

Please also send over any examples of work like this that you've done in the past and/or any examples of music composing work you've done.
