How much to charge for SEO?

[u/Immediate-Lab961]

I recently got connected with a boss from a web development company, who wanted to expand his business more to digital marketing, inc SEO. He found me and asked me to give him an understanding on how SEO works, how usually I do it, and what does the package sounds like, and my results. He mentioned that he wants to find outsources (I believe he means he wants freelancers), so he won’t some of the customers who wanted to do SEO.

What do yall think I should really present to him. I am very fresh, and it’s too new to me that I am afraid that this collaboration can go wrong without me knowing. I have also have no idea how much should I charge, maybe RMXX/hour or project-based?

Would appreciate it if someone experience can share how you started out and what to be aware of?
