Best self-storage marketing ideas?

[Brandon M.]

Recently acquired a small self storage building, your basic run of the mill self storage. On the lower end, no gate, no climate control, no office on location, just a block construction building with 42 garage doors. Property is not in a big town but gets 30k cars up and down the street each day, 1/4 mile from US19 which gets 50k cars a day. 7249 State Road 52, Hudson, FL 34667 is the address. 

The building sits directly behind a small strip center so it is not visible from the street, but the sign in front of the strip center does show my company name. Looking for thoughts on best/most effective marketing options to get the rest of my units leased up. Plan on doing a combination of: 

-Chamber of Commerce- costs $250 so possibly not.

- create a webpage for my company

-mailers/flyers/door hangers: directly behind my building is a MHP, I have considered hanging flyers on each door of the MHP and offering deals

-offering discounts to existing tenants if they refer new tenanty

-offering cash to businesses located in the strip center in front of my building

-Paying someone to stand on the street with a sign/banner offering deals

- pay per customer self storage advertising- I am looking into the cost of these now

-social media: I don't do much with Facebook/Twitter/other social media so I don't know how effective I could use these. 

Anyone else have any recommendations on what has worked best for them?
