I need 1 song mixed

I recorded my music on my own, and I’m not to really good at engineering. I need someone to bring it to life for me it’s little mess up like something a tad bit off beat and maybe to much echo. I need some to fix those problems for me that I couldn’t fix and make mix the track

Additional info:
I need the mixer to do some editing, time aligning and vocal tuning before mixing. The song is fully recorded. I just need mixing and mastering.. I need it by 1 September, 2021. I'm looking to hire a top pro who's worked on hit songs, and have the budget for that. I'll need you to master it too if possible. .
