Social Media Expert

I'm looking for a social media expert to help me in my agency. You will need to be independent, creative and reliable. I'd like you to have excellent graphic design skills (photoshop, canva). To save each other time I'd like you to come up with a sample (only 1 post) to understand how you think, design and work. It's more effective than many words.

The small task is the following:
You need to grow the Instagram account ---------- 1 post with the caption which can allow me to understand how you approach the account. That's all.

If we are a good fit, the cooperation will be long term and salary higher.
