Mailchimp template for scuba diving centre

As a highly experienced graphic designer, I am looking to create a Mailchimp template for a scuba diving centre. The main purpose of this template would be to send newsletters out to existing customers. I have some ideas for the general design and layout of the template, however the client has asked me to remain flexible to incorporate any changes or additions they may request. The client has also expressed that they have specific content to include in their newsletter, so I must keep this in mind when creating the template. With my skill and experience in web design, source manipulation and creative concept – I am confident I can create a sophisticated and engaging template that reflects the client’s needs and vision. The scuba school is called Scuba Evolution which is a PADI 5 star Instructor development center. The site to see www.scubaevolution.co.za
