I am now semi-retired, so not mastering every day. Unless I'm away, I can usually master your project within two to four days. Please send an email for a quote to: firstname.lastname@example.org
If you need vinyl mastering, I recommend you get in touch with Noel Summerville. Noel's been mastering almost as long as I have, and has a great mastering facility.
