The obvious answer may be both, but if you had to choose one....
Your best bet is to go it alone and sell it yourself. Offer it up on forums like #*$! and SitePoint, etc. At that price, you will probably find a buyer.
[oddly this forum won't allow me to mention one of the forums above - which is Digital Point. Just google it and you can find it - Both sites have a marketplace for selling ad space]
