Advice for marketing/renting storage in pole barn

[Scott Passman]

I acquired a property with a medium-sized pole barn in the back that I'm planning to rent out for storage.  This property is outside Indianapolis, so my initial thoughts are renting out to farmers for hay/food storage but would be open to storing almost anything.  Does anyone have any advice or suggestions for:

1. How to market available storage to farmers/general public?

2. Realistic rent expectations for storage?

3. Best way to optimize it for additional rental income?
