Do any Accountants offer a retainer sort of arrangement

[David V.]

I currently do my own bookkeeping and taxes (for five rentals) and am generally comfortable doing so.  However, what I need from time to time are answers to tax related questions that come up.  I currently have an attorney on retainer that i may email a few times a year to get answers to legal questions I have.  Do any of you such services? 

Regards
