Uh oh; all of my listings have sold! I need more Des Moines listings!

It's a nice problem to have -- I seldom have that many listings anyhow - I think five is my tops thus far, but recently I changed companies, brought my three listings with me.  Two sold in a week and the other within a month!  Now I'm fresh out and I need to get some new ones.  Believe me though, I'm not complaining.  :^)

I work in all kinds of ways to prospect for new ones but I'm wondering whether others here have had experience with companies like HomeGain or Reply.com?   I don't relish the idea of going out and knocking on FSBO doors, yet it has proved to be a fruitful method from time to time.  Generally, that's what I do if I'm short on work and long on time.   Or, I issue another newsletter. 

I do have some active buyers and prospects for future listings down the road, fortunately, but I'm just fishing for some ideas to fill the pipeline in a little different manner.  

Any one have suggestions for good ways to add some listings?  I feel very blessed to have been able to "sell out" in this slower market but it's time to get back to work!
