Hey Rob, first of all, welcome to the forum...
So, if you can say, where are you working in these days? For personal experience, working/running a hostel on its first times is amazing. We learn hugelly with on the job experience and every day we try to implement new things, ideas and marketing strategies mainly on-line, which is, in my opinion, the second best way to promote the hostel... The first in the word of mouth and on that, we can't do to much, just let this run... ;-)
