You initiated this thread by looking for guidance about where/how to look/shop for 5 letter domains. The thread has now evolved to where it reads like you're using the forum/thread to solicit submissions of domains that fit your criteria. Implicitly, if not expressly, you ARE asking for people to list domains "for sale" that fit your criteria.We don't allow that.
Alternatively, IF I were in the market - hunting for an unregistered 5 letter domain - the LAST thing I would do is have people post domain name suggestions on a public forum - where anyone can see the ideas and register the domain if unregistered. I've seen it happen. I, myself, have coined phrases in forums that were promptly registered as domain names. If it's public it's fair game.
You can try asking/advertising for domains for your business use at DNF, NamePros, DomainState and many other DF's that allow for commercial activity.
You might also try tweeting about your interests - offering a finder's fee.
I think we've exhausted our ability to offer guidance so, at this point, I'm putting the thread "out to pasture" - by closing/locking it. If my mod buddy Bucky wants to undo my act that's up to Her Highness. :P
