Advice on promoting vacation rental in Florida

Hi All,

Don't worry, I'm not about to plug my site/property here.

I own a vacation home in Key Largo, FL, which I used to rent to the same Canadian snowbirds every year from Jan-April. Unfortunately, they just told me that they can't afford to come down anymore. I was originally referred to them through word-of-mouth, but now I'm not certain where best to turn to find another long-term renter.

I have listings on VRBO and homeaway.com, which do fine for weekly renters, but not so much for long term.

Any suggestions on websites, realtors, etc. in Canada that might be a good option to promote my property?

Thanks,

Rich D.
