Make magical traps that cast the spell for you, and that automatically reset. You can have your low level followers/thralls be the ones harvesting it and running the hospital. A thread on this. There was a much older thread that went into a lot more detail, but I don't have a link.
Very nice. Quick question; Where are the rules for transparency with crafting? I remember it being stupidly good, but I can't place it, and still wanted to make Effigies. Effigies are awesome. Kalashtar Psionic Artificer might be the best way to do this.
I don't remember there being much overlap for crafting between psionics and magic. They both require different feats, prereq spells/powers, etc. IIRC, Secrets of Sarlona had some stuff on using one to meet the prereqs for the other, but I don't really remember much about it, as I've only briefly browsed through that book.
If you go with a Thrallherd, you can always pick up a crafter as your thrall...
