Acute fulminant hepatocellular failure
American Furniture Hall of Fame
Arizona Family Housing Fund
American Field Hockey Foundation
These are all valid agencies as well.
The .com is parked, and the .org is taken by the Advocates for Homeless Families. I doubt that the .org company will want to add .net to their list at a price you find fair. I would contact the other organizations and assess their interest. The air force and the american food health foundation appears to be good candidates, maybe the field hockey foundation as well, though foundations don't have too much discretionary income.
