Lobbyists don't like to be identified as lobbyists. So I'm guessing they won't come chasing after Lobbies.org.
For a retail buyer scenario, you'd need to wait for somebody to come to you -- unless, of course, you can identify an end user for a quick flip. I haven't looked, but nothing comes to mind.
So if you're looking to sell quickly, then you'll get only very low offers from domainers.
Most domainers offer $50 or less for 4-letter .COMs. So expect no better (and probably less) for the LLLL .ORG.
Lobbies.0rg ... You might get up to $100 from a domainer who likes single-word .ORGs in general.
