Beleive me, the carpet cleaning market in Ireland is no way near saturation point, no matter where you live on the Island. Apart from the training which you might receive from a franchise is it worth the extra thousands of euros which you will have to fork out, personally I do'nt think so. If you enroll in Ncca training course you will learn as much if not more. Get Joe polishe's marketing strategies and if you only put a fraction of it into practice you will become better at marketing than any franchise owner in your area.
Finally you will get all the help and advice you need on this and other cc boards.
