Sharepoint Intranet Builder

We are in the process of creating an intranet for our family office to keep all our documents and information in one place while also leveraging the information and technology to make our lives smoother and simpler. We would like a professional to come in and build that information management system for us on our domain. Each member of the family has various business entities and documents that need to be kept track of. Ideally, this system would also utilize Power Automate and Power Apps to automate and simplify tasks like receipt processing and document creation.
