Coorporate Housing Guidance

[Bryan Bruton]

I have a home in San Diego that I am putting on the rental market in August coming.  The question that I have is does anyone here know of a legitimate Coorporate Housing Agency that can manage my property to maximum benifit? 
I have been searching online and calling numerous companies only to get No answer or told that they only market their own homes or the last scenario is a company named Coorporate Housing By Owner that makes extraordinary claims toward keeping the home rented and generating a nice monthly income between $5,500-$6,500 per month, however this companies reviews are mostly all negative.
Any knowlege that you can share would be greatly appreciated. 
Thanks in advance
