Rental Management Co Recommendation for Memphis TN?

[Henry Der]

I have about 10 suites, 2 duplexes, one six unit.  Presently using a company that manages a very large portfolio (3000-4000) and I am finding a very high turnover in people I deal with, and seemingly slow to get things taken care of, and communications between the various departments getting missed, lost, and having to explain things multiple times.  Also the work quotes always seem to be on the high side, as they profit from any work done as well... Any recommendations of some companies I can talk to, to maybe make a change?
