I need to develop a identity to all the graphics I will use for my company

I'm building a small website which will sell online courses. Therefore I'll have several communication channel such as Facebook, Google Adwors (screen display), Instagram, Videos, the website it self, etc.. I will need to create an identity in terms of colors and shapes, as I want to have immediate recognition of my brand whenever I'm posting something. So, what I need in this project is: 1. Create the identity of my brand in terms of colors and shapes 2. A Facebook cover 3. 3 different templates for Facebook posts 4. 3 different banners templates for my main slider in the website 5. 1 template for Instagram post 6. 8 possible banner sizes templates for Google Adwords (Graphic display) 7. 1 template for the course main image 8. A business card By template I mean something that is like a "frame" where I can change the images that go inside of any art I'm posting in whatever channel, while keeping my brand always linked to any content posted.
