I need help mixing 4 or 5 songs in Logic and being shown how to do it

I'm very new to music production and need help mixing a few tunes I've made and want to be shown what I'm doing wrong and how to improve. Im in the Leeds region.

Additional info:
The song has less than 10 tracks recorded that need mixing. I need the mixer to do some editing, time aligning and vocal tuning before mixing. I'll need you to master it too if possible. I'm hoping to find a good mixer that can work with my limited budget. I don't have a hard deadline for this. .
