Convert HTML/CSS Page Into Email Newsletter

I have a web page that is programmed with CSS that displays great in a web browser, but it needs to be updated so that it can be sent as an email. This is a short deadline project, but it's pretty simple for anyone with experience creating email templates. All of the images and graphics already have permanent links. The only things you need to do are: recreate some of the CSS rounded corners as HTML tables with graphics of the rounded corners, specify font styles, change padding for images, and replace some of the more advanced CSS with code that works in an HTML email. Thanks!
