With this in mind, I'd like to suggest that you take a look at Canva. This online design program provides templates a simple drag-and-drop interface to enable anyone to create quality graphic materials- flyers, invitations, posters, blog and social media images, presentations and more.
The program is free to use and you can upload your own images to include in your design. Alternately, access the Canva design elements and stock photography at a low $1/image.
Not sure you can handle it? Easy... video tutorials are provided at the startup with more ideas and hints online. See the clip at the end of this blog and you'll see just how easy, and quick, it is to create great looking communication materials. Check out some of the designs below I've created using Canva.
