create some variations of HTML pages for downloads

We need to create HTML pages for a download site.

They should look like official download pages, with not too much info in them. Simply a download button, some title and info such as "compatibility (windows 7/xp/2000", and some random info you can find in download sites. It should look very clean.

Please make at least three different versions, including css. Also different designs for the "download" button. These should have a "hover" version, and a normal version.

Here are a few examples, but it still needs to be much cleaner than these:
(also without options of operation system choice, and without email field)

http://lp.sweetim.com/?lpver=62
http://xamarin.com/trial
http://www.splashtop.com/remote/desktop4windows/downloadstart
http://www.figure-me.com/2/
http://www.xored.com/products/f4/f4-downloads/
http://lp.bearshare.com/?sysid=2&appid=115
http://lp.sweetim.com/?lpver=122
http://lp.imesh.com/?sysid=1&appid=315

Please send some examples, or anything I can see if you got what I mean. It doesn't even need to be an example you designed, just anything online to see that we're on the same page :)

Thanks
