forgot to add: If you live in Tuscany, you are one very fortunate person!!

C'ho, c'hai, c'ha and so on are considered slang forms (they actually go against Italian rules, which allow ci to be elided only before i and e), and although widely used, "ciò (che non è ci + ho...) non vuol dire che tali usi siano ammissibili o tanto meno consigliabili nella prosa sorvegliata e negli usi standard dello scritto" (quote from http://www.treccani.it/magazine/lingua_italiana/domande_e_risposte/grammatica/grammatica_060.html that contains a grammarian's opinion). In other words, it's substandard Italian and you should avoid it outside colloquial contexts.

P.S. The political situation is much worse in the rest of Italy...
