Query for free time by provider

[Tom Zaccaria]

Need a query that returns free time (time units) for a provider over length of time.
For example, Doc A works three 8 hour days a week. That is 24 total hours. We us 15 minute intervals so that would be 96 time units total.
I want to find the number of time units that were free as in cancelled or broken or never scheduled.

If you can direct me to something that is already written and needs modification that would be a plus.
Thanks,
drtmz
