I need shuttle transportation from Tampa/St. Pete airport to Ocala, Florida any suggestions? -

There is not shuttle service, unless you mean small plane,(puddle jumper) between Tampa/St. Pete and Ocala but there is Greyhound .

Shuttle liner operates for about 40 bucks each way

Check the Tampa airport website and look for shuttle bus services. See if any service the Ocala Gainesville area.

No shuttle. Cheapest fare would be Bus, rental car or Uhaul. Hitchhiking is pretty cheap.
