I need a beat for a song and I need spade mixed and master

I wrote songs and I need a beat that makes them stand out, they are aggressive rap songs and in addition I would need to mix them and do the master, to write I don't use real inspirations but since I was a child I listen to Italian rap like gemitaiz, Madman, Nitro,... I would like to get my music to as many people as possible by putting it on spotify, youtube, soundtrack,... and I don't have a deadline

Additional info:
The song has somewhere between 10 and 30 tracks recorded that need mixing. . I'm interested in working with a very experienced mixer. I'll need you to master it too if possible. I need the vocals tuned as well. I'm an indie artist. I don't have a hard deadline for this.
