I need wordpress Email template development design

I need a professional developer and designer able to edit the design of my website email templates.

The templates need to be edited manually or with some plug in, not with mail chimp or similar,
because my website will send unlimited emails each month. These are just automated admin emails
sent to customers (order dispatched, order received, order cancelled, etc...).

There is some error happening on my wordpress account when i try to use plugins so the developer
needs to have the knowledge to also fix these issues.

Please contact me only if you have experience in wordpress email design development.

All needs to be done is to change the design of all the email standard wordpress template.
(logo, colours and font matching my website ,etc...)

You will then tell me how I can edit the text of the emails, and I will do that part.

I need it done within 24 hours.

Thank you
