I put this forward in another thread, but has anyone given any thought to reaching out to the local community colleges that have technical programs? I know TCC, DCCCD, and CCCC all have vocational stuff like welding, wood, automotive, etc. where people who graduate might be looking for somewhere to practice those skills, since access to academic facilities ends when your tuition does.
Also, has there ever been a serious discussion of using AdSense? Seems to me like an ad on a Google search from a user in Dallas, for high-investment tools like a CNC router/laser cutter/auto lift/pottery kiln, would be a good way to snag eyeballs from people who have specific needs that could be served by what the space has.
