Joe,
I'm not a professional
tile fixer, and my first big
tile job was to lay porcelain tiles over my kitchen floor. I used a cheap and nasty dry cutter and found it, not easy but not difficult or hard either. the tiles were tough to cut but not impossible.
speak to your tiler about your concerns. if the company you have appointed to carry out the works are a fairly long standing organisation, they should surely have the right equipment to cut porcelain tiles.
be bold and ask why the price is now doubling because the tiles you have chosen are not ceramics. there should be relatively little difference between ceramic and porcelain if the
tile fixers have experience of fixing both.
also, if you agreed a price up front, then the tiler should either stick to that price or at least come to some kind of compromise as to the increase in price. i suspect he's trying it on. challenge him and don't back down. make sure you get the quality job you want at the price that is sensible for the work carried out. if he puts up a fuss, offer to pay him for the work he's done already and end it there. find a new fixer and move on with your bathrooms.
