MS Office 365/Teams Training

We are a local Charity - YMCA in Redhill Surrey. We have had MS Office for some time but during Covid only partly rolled out across all staff and we have just made do with learning as we go. I work as an Exec Asst for the CEO and he would like a few hours with a Freelancer with experience providing unstructured 1:1 training and advice on Microsoft Office 365 applications, including Sharepoint, Outlook, etc to find quicker and smarter ways of working between us - getting better organised. So we are looking at potentially about 1-3 hours exploring how we are using MS Office currently and improvement/better ways of doing. If you are experienced with MS Office 365 and have knowledge in these areas, please let me know. Thank you.
