You can give away free staff to attract visitors, like free beers..
Now seriously: you can have a student portal. There is a lot of software available that students can use (i mean school and higher) but people just don't know about it. Example: free C/C++ compilers, K3dsurf, Kplot, octave, gnuplot and other. I'm still learning how to use all this stuff for my needs, and it would be great if i had someone to chat about this.
