Animated landing pages

I want 3+ landing pages created. The sole focus of the landing pages is to get the customer to click and download my toolbar. The toolbar is to allow customer to use 10,000+ smileys on their IM, email, chat, facebook, etc. The url below is a good converting LP and want at least one of them similar but it can't look too similar as that would violate their copyright. The work should be original. [login to view URL] I want someone experienced in designing LPs that convert and not necessarily just how nice they look. I would rather have an LP that doesn't look that nice but converts 1% better. Of the 3 landing pages I would also want a few options on each one that I can switch out to see if conversions increase. This could be as simple as different colors for buttons and links or more complex and a different color scheme other places such as backgrounds, etc.
