A little south of Preveza is Nidri, on the east coast
of Levkada. Walk south out of Nidri about 500 metres and you'll find Phil's stainess steel
shop on the right. All the yotties there know him. He's a Brit, been working in that area for about nine years to my knowledge, always has a waiting list of jobs, and I've only heard praise for his work. I chose him for a slightly smaller stern job than I believe you'd need.
He'll quickly tell you whether the job is within his scope
or not (depends a bit on your size) and he'll warn you if he can't arrange for the finished item to be polished up to a really stain free finish (I would have had to have waited four weeks so I chose not, to find much later that his finish was the same standard as the rest of my vessel's stainless).
While you're travelling there, you may find my site useful!
