Hi the price on SideProjectors is a typo - I need to fix that. No wonder no one has jumped on it :)
The usage is really quite low - I never spent any time marketing it unfortunately. It was easier for me to use the site than manually create the collateral that I wanted so I built it.
If you'd like more details feel free to email me (address in my profile).
Edit: I see you have it listed on SideProjectors. Is $25,000 correct or a typo? Doesn't quite line up well with 10 users a month :)
