The core of a song is melody and lyrics. If those aren't great by themselves, than you can polish something all you want and make it sound good, but it won't be something that lasts.
And the production of a song can make or break whether people pay attention to it or not.
Producing can include addressing a lot of things: lyrical/melody guidance, song dynamics, instruments that play over each other, chord progressions, arrangements, flow, length, groove, etc.
The bottom line is: I want you to have the best version of YOU. I'm not a producer that changes your sound... I'm one that helps yours be heard.
