I need a mailchimp editable template designed and installed

I need a MailChimp Template that is easily editable through drag and drop, that can be used for future emails, and there are two different audiences, so I will need the same template, but one with one menu and one with the other. These will need to be installed into MailChimp. I expect unlimited revisions until it meets the requirements.

The first template design should be completed soon as the deadline for the final delivery is November 27.
