~Please Help~

I have used all the online (free and paysites).

I am trying to find a skiptracer (sp?) to contact a guy who owns 1000 acres in Central Illinois. The land hasn't been hunted in 5 years..The owner lives in Florida and the land is just sitting there. If I could contact him, I'm sure I can get a good lease price due to the fact nobody else has contacted him.

Problem is, mail is being returned from the address registered with the county and I cannot find a phone number. Does anyone know someone that does this kind of thing for a living and can help me get in touch with the guy?

Thanks a bunch.
