Hard to say.
Do up three quick and clever 'viral' landing pages maybe, like you see with Launch Effect (Launchpad?) for WordPress with a few unique and hooking blurbs tailored for each, with a nice looking logo, and see what happens with subscriptions and shares over the next couple months.
Definitely worth more if they have traffic, and you can do the above in a quality way in an hour.
Just my two cents!
