Configure SharePoint for External Collaboration

I need an expert to set up a SharePoint folder in our existing Office 365 environment. The purpose of this setup is to enable collaborative work with people outside of our organization, specifically clients, partners, and freelancers. Key Requirements: - Provide external users with 'Edit and upload' access: This includes clients, partners, and freelancers who will need to modify documents and upload new ones. - Restrict access to specific folders: External collaborators will only need access to certain folders, not the entire SharePoint site. Ideal Skills and Experience: - Proficiency in SharePoint and Office 365 - Experience with setting up secure, collaborative online workspaces - Ability to configure access controls on a granular level - Knowledge of best practices for external collaboration in a corporate environment.
