I have like 7 songs I poorly mixed so I need to get a good mix and a master

i have 7 songs of hiphop to mix/master . Some of them are hiphop boom bap and others are trap . I tried to mix but the result is not exactly what I pretend and I also need to mixed them . Maybe we try with one of them and if I like we proceed to the rest of them? Thank you ,ass Chari

Additional info:
I'm looking to master at least 5 songs, possibly more. I don't have a hard deadline for this. I need the mixer to do some editing, time aligning and vocal tuning before mixing. I'm an indie artist. Check out the song I attached. I'm hoping to find a good mixer that can work with my limited budget. I'll need you to master it too if possible.
