Nice GEO domain. If you find someone in Spain looking for that type of GEO domain you could get several thousand. Otherwise, probably about $15-60. I'd contact Web Hosting companies in Spain to get a good price for it.
Registration fee to xx to a reseller and xxx-xxxx to an end user; there are quite a few other (country)webhost.com / (country)webhosting.com's available, so it's nothing too special. Your best bet would be to email some Spanish hosting companies and see if any bite.
