Graphic Designer Wanted Part-Time

I am looking for a talented graphic designer to help with on-going projects. Specifically, I am looking for someone that is comfortable handing tasks similar to the following:
-creation of company newsletter for print
-magazine ads to specifications
-social media posts
-in-office signage, posters
-postcards, marketing collateral, etc.

The design work does not need to be lightning fast but clear communication on when it will be ready is critical.
