advertisement for rental flatfee MLS ?

[Kevin McDonald]

What method do you use for advertisement rentals? I currently use Zillow and craigslist. I have had best luck with Zillow but was thinking about also trying a flat rate MLS.

I was not sure what to do with commission, I know typically in my area if an agent lists the property, shows it does all the contracts/background checks he gets one months rent as a commission. 

For commission I was thinking a flat rate like $500 or something.  I do my own back ground/credit checks, my own leases, etc.... So all the agent would do is refer the person.  Not sure how I would list that. 

I know a lot of the flat rate web sites say they will refer any calls right to you and not a realtor but do they really do that or will they have a friend agent contact you to get a commission, I am not sure.

I am just trying to maximize my rental advertisement and was curious what others use.
