Need 2 songs mixed

I’ve finished recording 2 songs, I need them engineered/revised to improve the quality of my voice, and the base. The song sounds off when you’re in the car playing it off you’re Bluetooth. I need it clear, the 2nd song The same thing. Voice Quality, bass quality, and overall sound. Deadline October 20th, if possible. If not contact me asap!! Each song has around 10 recorded tracks where i punched in and out. The genre is Hip Hop & R&B. A comparison as far as sound would be NBA Youngboy, Polo G, & lil durk. Contact me back asap please !

Additional info:
I'm an indie artist. I need the vocals tuned as well. Check out the song I attached. The song has somewhere between 10 and 30 tracks recorded that need mixing. I need it by 20 October, 2022. 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.
