I think that almost all of the value in this domain is derived through its development potential. In my opinion, it probably makes very little simply as a parked domain.
Thus, any additional value would have to be added to the domain through an extensive development and marketing strategy. The words do make sense to me, so there is some value to unlock with development. But I have a bit of a difficult time seeing it on a Billboard or in a Magazine as it is right now.
I think $5k is a fair offer and is most likely from someone who has a business plan to back it up. Granted, $5k is nothing for someone with a business plan, but at the same time, how many others are you willing to wager have a specific business plan for this domain?
In conclusion, I would take the offer, as it's a fair one in my opinion.
