Create engaging Linkedin posts and potentially develop a comprehensive Linkedin strategy

We are a trade association representing the producers of the mineral barytes. We set up the LinkedIn account this year without much of a budget to post, mostly focusing on promoting our Annual Conference. Please find the LinkedIn page here: https://www.linkedin.com/company/barytes-association. We would like to expand our activities as of next year and look for an agency that can take care of that. We expect to have between 12 and 24 posts per year. We mostly anticipate posts to promote events, report about activities, increase visibility and generate membership interest. The factual input would come from us, but we would need you to bring it into a successful format.
Your service will only be needed in 2026. It would be good to receive offers for 12, 18 and 24 posts.
