I can convert your PSD into a working HTML email that is mobile responsive and work on most email platforms.
For use with Mailchimp, I include mailchimp coding language for the template to be easily editable when creating your own campaigns. It includes mobile responsive version as well.
All my email templates are custom coded. I'm also familiar with Mailchimp's drag and drop editor, and I can use that to create Mailchimp templates as well requested.
Looking forward to working with you :)
