Looking for new tracks

What do you charge per track you produce. I’m an artist with label distribution deal from orchard. I have 10 songs done for my first release. Looking for new tracks . Thank you

Additional info:
The tracks are cleaned, tuned, and and the song is ready to be mixed. I don't need the song mastered. I'm looking to hire a top pro who's worked on hit songs, and have the budget for that. I want a beat made.
