Need a production, mixing and mastering of a track

I’ve been asked to write and perform a song for a high end wedding. Working on top line and lyrics this week, I’m thinking uptempo type Robin Dancing in my own / Gaga Shallow style. Looking for a producer for the backing track and also mixing and mastering of vocals.

Additional info:
. The song has less than 10 tracks recorded that need mixing. 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 need it by 1 September, 2021. I need the vocals tuned as well.
