Looking for Social Media automation including Canva, LinkedIn and Insta

I am an avid LinkedIn user with a massive following, something that I have nurtured over the past 5 years.

Since there are endless automations happening alk over, I would like to explore the below idea:

1. A title is added to Google Sheet - Trigger

2. The flow runs by giving 2 to 3 AI generated variants, ensuring LinkedIn post structure. This is broken down into smaller chunks, which will be used by Canva and fed into a carousel to be used on Instagram.

3. Once the content is structured, a review email will be shared. Upon approval, the post is posted on the Personal LinkedIn account and Instagram page.

I am sure it's not a huge thing, and I am assuming there are already templates available that I can download the .json file and explore the n8n as an option, but then hosting becomes a pain.

Anyone out there who would be happy to take it up as a project?
