Hi!
I would be happy to work on this project for you and can have it completed ASAP.
I understand your requirements (however I cannot access your website at the moment, an error is displayed). I have experience in custom HTML, CSS and PHP development for Wordpress, and also have experience integrating with MailChimp.
I am also located in Australia, which makes communication much easier.
Looking forward to working with you
Thankyou,
Hayden
