Are you being too nice not posting a link (or maybe you have a technical reason)? I was a little hurt when a friend said I wouldn’t be a good business man as I wasn’t cut throat enough. My friend wasn’t being entirely wise but there was a little truth in there.
I have been selling a subscription service to schools now for 10 years, enough for me to work part-time on the project. Biggest leap in customers I had was through an educational fare. It cost about £6000 to exhibit if I remember.
