You do not need a finished song to start.
Find the sound and choose the right references.
Shape the beat and arrangement around the vocal.
Capture the vocal and get the performance right.
Edit, mix and prepare the record for release.

References can point to the sound. The record still needs to feel like you.
Bring a melody, voice note or reference. That is enough to start.
Send it. Mertz can rebuild the beat, change the arrangement, record new vocals or help finish it.
Send the files and references. Mertz will tell you what he needs.
