Need 45 min album mixed in Logic Pro X

Hi, I need 10 songs mixed and mastered - they're about 45 min in total. I have 8 of them recorded on and I'm mostly happy with the recordings but some of the vocal tracks aren't the greatest quality (because of background noise). All files are in Logic Pro X - mostly consisting of apple loops and my own MIDI compositions. I would like to get quote on what it would cost to audio engineer all the files whether per song or by project.
