Technical side - neat, very neat. I like it a lot.

Business side - the recurrent pricing model does not make any sense whatsoever. Unless someone is actively developing the site or manually changes the content on a daily basis, per-use charges is what is expected.

There is certainly a market for enterprise-ish application of your idea, when the site is routinely modified several times a week by marketing and product people and such. But then your Basic plan basically will easily cover the needs of a small/middle size corporation with extensive online presence. Additionally, beware of the existing services like Keynote that already target that segment and that will be copying your idea in a matter of weeks.
