Create engaging copy for multiple landing pages based on core site

We need someone to take our site's existing content and write the copy that we'll use on several dozen landing pages. You will not need to do any design work, we just need you to focus on writing engaging "take action" copy. Experience with gateway/landing page writing is a plus. You will have access to plenty of content to draw from but we don't need ALL of it rewritten. This isn't a total re-write situation. Basically, we just need someone talented enough to take what we have, condense it down, and provide several versions so we can test market to see which copy performs best. We'd probably be looking at 1-2 pages of standard typed content on average per site. In your quote, let us know what you would charge for THREE versions. If all goes well with those three, we'll hire for more.
