Need 3 songs mixed and mastered

My boyfriend is a great musician and has finished recording about 3 songs. We want to get them ready for release. Please help! thanks

Additional info:
I'm interested in working with a very experienced mixer. I'll need you to master it too if possible. . The song has somewhere between 10 and 30 tracks recorded that need mixing. I need the mixer to do some editing, time aligning and vocal tuning before mixing. I need it by 23 May, 2020.
