In need of a songwriter

I’m in need of help writing lyrics. My goal is to sound like post Malone in his new album “Austin” and I can’t seem to find the sound in my voice. Please contact me if you’re interested in helping me . Thank you

Additional info:
The vocals will be used in a commercial release. I'd rather pay extra for the writing to be ‘work for hire' and not share publishing.. . I'm an indie artist. I need a song written from scratch - lyrics, music, and vocal melody.
