I have a few ideas that I need to validate. Is there any offering that lets me quickly create MVP sites? I'd need:

Theme Forest is a really great site for finding beautiful, cheap front end templates. Perhaps that could be of use? You can usually get this up and running in minutes. Put a Wordpress backend on it, and that's your CMS system covered also.

Try Drupal Gardens Drupal has plenty of community modules with features similar to what you're looking for, though I'm not sure if Drupal Gardens provides that level of customization. Also, it's largely php/mysql based, not in ASP.NET.
Unbounce lets you collect emails and has predesigned themes. I haven't used it myself, but from what I see, you can get a landing page about in about 1 hour.
You could also try getting an invite from LaunchRock, which is a landing page service similar to Unbounce, but has a more viral nature to it.
For building your site, use Wordpress and buy a premium theme on ThemeForest. You can get a beautiful looking sales site up in less than a day.
I would just install wordpress, install the mailchimp like plugins and be done with it. Pick free themes for each one and you will be all set in few hours.
I use mediatemple and servint and both of them have wordpress as one click installs. So I can setup multiple websites in less than an hour. I use blogdesk to add content to each of my sites.
Looks like weebly, the free website service - www.weebly.com - supports asp.net. See the comment here that looks like it's from someone at weebly - http://askville.amazon.com/weebly-make-website-put-rating-system/AnswerViewer.do?requestId=50381822
