I would strongly suggest speaking with them on the phone to determine their level of professionalism, and subsequently, their seriousness in paying the right price for this domain.
As for development, I would tell them that you were planning on developing it into a travel site for Las Vegas, until they came into the pricture and showed interest in buying. You're a business man afterall, profit upfront is the same as longterm profit, if you need the money right now, and you have a buyer ready to bite at an optimum price.
No harm in calling their "Big Clients" and verifying that they have in fact done work for them in the past. If the Big Boys claim they haven't, then i'd recommend you call them on it, and ask them to state THEIR intentions for the name -- and pressure a little more, as in, they will have 48 hours to accept the deal, or the offer is revoked.
Just my advice.
