We love the cartoon style (I am sure there is a more correct graphic design word...) of MailChimp and Exam Professor. They are very modern in terms of website looks and have a bit of a macintosh design aesthetic to them which we love.
It needs to look fresh and have a social networking vibe to it.
We will be creating a website around it and so the icon/seal/logo/certification you create will need to be the driving force behind the fresh look the website will have.
Have a look at
