Looking for content for IG business niche

I am starting a business niche for IG and I want to upload those info graphic posts that you see on IG pages, and I was wondering if anybody knows some shortcut in creating the IG. Like if there is a website where I can download a bunch of those info graphic post and then upload them to my IG or if there is some sort of info graphic generator I can use. Just looking for a way to create content faster then sitting down and spending 3 hours everyday just creating info graphic posts.
