Customer service is unresponsive.  

Could be the tenant is not using the service, doing something to attract roaches or the exterminator isn't doing their job.

It will ultimately depend on price point and what level of service you want to provide. 

Nature campaigns, direct mail, text services, accounting, etc all in one place. 

I would suggest a good PM to start if you don't have a solid background in hospitality or at least something in the service industry.Self-managing can save a ton of money if you know what you are doing. 

Do you offer such services?

I can find the broke and impatient all I want at convenience stores and sports bars.Something to be said about paying for a service.
