I need 4 songs mixed and mastered

Hi. I’m writing from norway. I ‘ve recorded some songs in my Home studio. I need some outside ears to finish my project. 2 pop songs and 2 instrumentals. I use Pro Tools . I play all the instruments, but my main instr is guitar and vocals. The songs have around 30 tracks each. How much will this cost and what is the prosess going forward? Best regards Jorgen Jensaas

Additional info:
The song has somewhere between 10 and 30 tracks recorded that need mixing. Check out the song I attached. I'm an indie artist. I don't need the song mastered. I don't have a hard deadline for this. I'm hoping to find a good mixer that can work with my limited budget. The tracks are cleaned, tuned, and and the song is ready to be mixed.
