www.dalyanmermer.com for marble they are a very good company run by a team of brothers. To give you some idea of how good they are they did the marbling and tiling at pegasus palace in Sarigerme and the Dalyan Resort here in Dalyan. But they do undertake smaller jobs as well as we employed them to lay 1 single peice of marble.
They speak a little English probably enough for this job.
