How much should you charge as a beginner for LinkedIn ghostwriting?

Hello,
If you are a beginner, how much should you charge? I know how to get clients from LinkedIn, I just don`t know how much I should charge as a beginner writer.
I create organic leads through LinkedIn content. Could I charge 1500$ for 36 hours of work? 20 articles and 16 days of engagement(for 1 and a half hours ) with followers and other influencers, and commenting strategically in order to get more following and leads to the LinkedIn account I`m ghostwriting for?
I`m from Eastern Europe

Do you mean 20 full articles or shorter LinkedIn posts? The engagement part already adds up to 24 hours, leaving 12 for writing all 20.

Unlike Facebook or Instagram, content on LinkedIn is geared toward professionals, B2B (business-to-business) interactions, and personal branding; as a result, the platform often yields higher conversion value. Based on international market rates, costs typically range from approximately $25–$50 for an individual post, or $200–$500 per month for recurring monthly service packages.

I would clearly define what's included in the $1,500 package, especially revisions and engagement work. Otherwise, 36 planned hours can easily turn into much more. A short paid trial might also help establish expectations with the first client.
