Mixing and mastering my music

I finished producing the music, but I want my music to sound more professional.

Additional info:
The song has less than 10 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I'll need you to master it too if possible. I'm looking to hire a top pro who's worked on hit songs, and have the budget for that. I don't have a hard deadline for this. .
