Unified Social Media Branding

I'm looking for somebody to help me unify the branding of my social media profiles. This includes creating a unified look and feel across Facebook, Twitter, and Instagram. I want a branded plug and play file for events and posts on our social media platforms. i have included a few examples as well as my logo. I need a place where I can put text and information about the event. I am constantly finding posts on canvas and changing the info but its just not looking consistant across all platforms and times of the year.

We did one for music and such and i have included it as well. I want that same look and feel, minus the picture in the background since this will mostly be text.

Colors need to be similar to the screen shot provided. It also needs to be the size of a a instagram post box.
