Logo and Business card design

I want a logo for All Notary Signing Services. Which is a Notary service providing general Notary work as well as Loan Signings. I want something with either a stamp or pen signing. This logo will be used on marketing materials such as website, social media, business cards, and leave behind materials i.e postcards and flyers. I want something that is simple and color of blue and green. Below are samples of the kind of pen or notary stamp.
