Design Mailchimp Template for Accounting Services

I would like to design a template for my accounting services in Mailchimp. The template must include (1) Xero and partner services (Receipt Bank and Vend) and how they work together hand in hand and (2) our accounting and support services. The template must include indicative hyperlinks to our website, social media sites and contact details, and can be tracked via Mailchimp. The template contents must be editable in Mailchimp and not a flyer uploaded to Mailchimp. There must be a clear "unsubscribe" link. Further details will be discussed upon award of project.
