Need 4 tracks mixed

We´re producing 4 tracks for argentinean artist Abril Sosa that we need to get mixed. I´ll send a track so you can check it out. The vocals aren´t final but you´ll get an idea of what it about. We´re looking forward to have them finished by the end of July. We would also like to see your price list. Thanks for your time Juan Ponte

Additional info:
The song has over 50 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. Check out the song I attached.
