Need help looking for travertine tiles

[samdale]

I need some 40.6cm x 40.6cm filled travertine tiles. I only need around half a dozen or so but the only place I can find is online and wants a lot of money for delivery and the closest collection point is Oxford

These are what I'm after

Is this the sort of thing a local tile place would be able to source for me? Any help much appreciated.
