The short answer is yes, I do offer unlimited revisions. To a point.
Unlimited revisions are included until you approve the mix and we print the final mix package. Once the final mixes are printed and the session is backed up, the project is completed. After that, if you discover anything that you want to change or revise, this is charged at a nominal hourly rate. I keep backups of all sessions indefinitely.
Because of this, please review your mixes carefully and make sure everything is perfect before you sign off and approve the mixes.
