I need a mailchimp email and template (so we can edit in future and re-use)

Hi there. We've been using mailchimp for years with a template I made years ago using dreamweaver, its ok but I want a new template that looks identical to our website so clients see pretty much the same in their inbox as they do when they visit the front page of our site: http://www.sidewaysfilm.com/category/all-titles/

We're a documentary distribution company and we send these mailouts twice a year to all of our clients so they know of our new documentary titles. You can see from the link that the mailout would include 12 images and 12 bits of text, and above this perhaps a small logo and a line like 'new titles for 2016'.

We'd like to be able to edit it ourselves, either using dreamweaver or something else that you suggest / as you advise, baring in mind that we're of average skill with these things! I think this job should be quite easy, you'll see if you visit our site.

Thanks!
