How much for this shoutout?

Hey everyone :)

someone contacted me yesterday on one of my accounts to offer me a shoutout for a mug to sell on his Shopify shop and I would have liked to know how much you would ask him for this kind of service (I am completely inexperienced, I have never done this before).
I have 7000 followers, 600 likes and 40 comments on average on my last 10 publications and he wants to make a post for 24h… how much will you take for that?

Thank you for your answer, hoping that you could help me I…
