I can't see a train or bus service to Scigliano (which is not to say there isn't one though! just that I can't find it by the usual means).
Here's a link to a taxi firm that is based at the airport.
It might be worth emailing and asking what they would charge (there is a page with example fares which also might give you some idea).
.::Calabria Taxi |Servizio Taxi Lamezia Terme Aeroporto e Stazione FS::.
Or how about emailing the comune and asking them the best way to get there? Part of their website is in English and they encourage contact:
