From digital to dia slide

[Matjazz]

I've been looking for a shop that could get my pictures to dia slides. Ive found several quite expensive shops in Germany (searched "diabelichtung" on google.de). Fortunately there is an ebay.de store with acceptable prices but it doesn't support paypal and accepts pictures only on CD by snail mail which is kind of old fashioned to say the least.
The trouble with possible UK or USA shops is that I don't know how to search for them. I get a bunch of results offering me dia scanning and slide show software. Can anybody help me find those shops? What should I type in google? In which category should I look on ebay?

Thanx
