Phone support. For sonar .will pay for tutor

Where are you located? You'll do better if you can find someone local to you who can physically come over and show you stuff. I say that as someone who provides telephone support (not for audio software) every day of the week. Even with remote-control software and Skype, there is only so much you can communicate over the phone.
