Nikolaus, I agree you should first play with something that is available.
The information I got is from eurocircuit.com, The price is based on 4 layer 150 * 60 mm; just a wild guess of the size and layers based on standard technology, but giving an indication. More about the possibilities can be read in http://www.eurocircuits.com/images/stories/ec09/ec-services-leaflet-uk-english-4-2010-v2.pdf. I did not check any guidelines and requirements, so hard to say what suits. If somebody could provide more detailed information or point in a direction, a more serious price could be obtained.
