I need help with expanding the capabilities of my Facebook "Fan Page" that I've created for business. I've viewed some of the Youtube "How to's" to add a "call to action" button, but it only allows you to set it up as a direct link to your website. I think a link to a link to a ... is too involved and I won't get any "click-thru's" to get anything accomplished. I want to create a "call to action" button that can be designed to send out a "online newsletter" (or some other e-bonus) to those who opt-in and provide a means for lead capture back to me.
Something
very simple, like "click here" > a smaller window opens with a heading (E.g.: "Get your free newsletter...") and "type in" boxes for name, e-mail and zip code. Lastly a "send" button.
Any & all help would be greatly appreciated.

Thanks!
