A poster (11"x17"), flyer (8.5"x11"), square image for instagram 1080px by 1080px, and rectangular image for X 1024px x 512px

I am looking to create an effective and eye-catching social media campaign that will help promote my product/service with posters, flyers, and images. The campaign should be about motivation and for people to feel inspired to workout and stay active. The main phrase or slogan just be "Don't think, Just do!" The effort of the social media campaign is that every time someone goes to workout and better themselves they post it on any social media platform with the hashtag "Don't think, Just do!" I am not looking for specific design elements or branding guidelines and would like the freelancer to come up with creative designs that will help make this campaign successful. I am leaning towards Military Colors manly Marine Corps color scheme, but feel free to be creative and suggest other color options. The project will include a poster (11"x17"), flyer (8.5"x11"), square image for instagram 1080px by 1080px, and rectangular image for X 1024px x 512px. You can use Pixlr X for this or any photo editor. Please make sure I have four things as listed above. With your help, I am looking forward to gaining more visibility and growing my business.
