Design an email with Mailchimp

We have a well stablished company based in Spain and we want to send attractive, professionally designed emails to our client database, using our account on Mailchimp. We have our marketing strategy well structured and all we require is the design of 4-5 emails linked to our site, clubamistad.com. This project would just be one first email, and it could be extended to future emails if the result is well executed.
