I live in Greece and finding these was just as difficult. For the utensils and baking equipment I ended up settling with buying online from the UK. There are many cake decorating online stores to choose from, there are plenty on e-bay as well and the shipping was very reasonable. For the ingredients I settled with substituting those I couldn't find. If there is an ingredient you can't find, try substituting it with what you can, you'd be surprised of the results. For the packaging supplies you can start by checking the yellow pages or business pages and looking for the companies that provide that. All the bakeries are getting them from somewhere and you need to find where. Sometimes these suppliers are hard to find (well they were for me) and it does help to get people in the trade tell you who they are and where to find them. I had done a lot of searching with the yellow pages and had found a few, but I ended up get the best help with that from friends of friends who delt with them already. Hope you find what you need, good luck!

I usually end up ordering my supplies from amazon.de. They let you pay by bank transfer, which is REALLY great for me, since I don't have a credit card. The only thing is that some things are only shipped to Germany, but that's the best I've been able to find.
