Yes, they should - just saw there is the contact form below in the first link (it's not very overseeable even in German...). Overall they don't seem too bad. If you start from Wien I suppose one should find something as well. It only seems to me that they shuttle til Linz and not further. But maybe you can talk them into something else or they should know the next competitor along the river -
faltboot.org has a wiki
with river descriptions and possible starting points. It could give ideas for alternative starts. (no. 4 - or just here
Einsetzstellen - where you can put the boat in or out)
