Part time controller?

Hello all

In the past I've always done all my own accounting / bookkeeping/ bills etc. I have been looking into using a part time controller who would handle all the financial aspects then report them to me. There is Of course there is a cost for the service but I feel the time that it would free up for me could be worth it. I was wondering if any of you use a service like this and what your experience may have been.

Thank for your help!
