Need 10-12 songs mastered

I’m currently working on a project that will be between 15-20 minutes long with 10-12 songs that I’d like mastered. I’m friends with Alien Eyelid and Brett is mixing/producing the album. It’s pop rock/electronic/power pop stuff. The songs are primarily very short (1-2.5 minutes). It might not be ready for a few months still, but I was hoping to get a ballpark quote from you just to know what I could possibly expect. I love your work and would love to see what you did with the songs. Thank you. - Stefan

Additional info:
I'm looking to master at least 5 songs, possibly more. 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. The song is mixed and ready to be mastered.
