Newsletter to use through mail chimp

Hello,
I need a newsletter designed to use through mail chimp. I believe they have templates you can use. I am super busy with other client work and cannot get to this right away. I have company info, logo can be pulled from website as well as additional information. This will be sent through mail chimp and my clients email list. I need someone with experience who has worked with / used mail chimp before as I have hired someone to produce newsletter and it was not compatible with mail chimp.
