Mailchimp newsletter design

I am looking for a designer who specialises in mail chimp newsletter design. I don't think I require a bespoke template design and own coding, but using existing templates to be customised.
I am working on a welcome letter, which clients receive when they subscribe on my website and then a regular newsletter template which could possible be the same ??
I am looking for a designer who has experience in the health & wellness sector and a good eye for colour, design and understanding of branding.
I am looking to create a banner at top of page which uses an image and incorporates my logo. ( Please see attached)
Please see my website www.kristinakoestler.com for reference
The images attached are also for colour guidance plus a soft pink which I will share in more detailed brief.
