Baritone/Bass Vocalist for one Verse Section

I need a baritone or bass vocalist to provide background vocals for recording a track. The project involves a mixed genre of Pop-Rock-Electronic music. You don't need insane technique, because the verse is more similar to talking than full on singing, but it'd still be considered singing.

Key Requirements:
- Perform unison singing for the track.
- Have a baritone or bass vocal range.
- Have a decent quality microphone. An iPhone microphone is good and preferred.

Ideal Skills and Experience:
- Strong baritone or bass vocal range.
