I'm not paid to say this but I highly recommend Unbounce for landing page creation -- simply a fan of that service. It is available in this month's free Appsumo bundle http://appsumo.com/hacker-monthly/
(Visual Website Optimizer is also in the bundle -- and we've got a nice plugin for Unbounce!)
It's a good offer if you want those things, but note that the bundle is bunch of free[1] coupons, not free products - that is, you'll still have to spend money to get the benefits. (E.g. you get a free upgrade from a $25 to a $125 plan.)
[1] Where "free" means "in exchange for spamming your Twitter/Facebook friends".
Oh yes, didn't notice that. We offered VWO 3 month custom-plan for free, so assumed all services on the bundle are free. But great that you mentioned it here. (I now notice that only Visual Website Optimizer and KISSMetrics are completely free. Rest require some kind of purchase)
