Where can I go to talk to a CPA for a single tax question?

[Michael Zagorsky]

Does anyone have recommendations on where I could talk to a CPA online related to a single specific tax question? I normally just use Turbotax, but I am converting a rental home the tenant trashed to a second personal residence and want to talk through how we should handle the expenses associated with it as the repair expenses exceed the rent collected for the year.  

I looked online but did not really find any sort of advice-by-the-question services out there. Just looking for a flat-rate service for a 15 minute question.
