create intranet for a supported accommodation provider

I'm looking for a developer to create an intranet system for a supported accommodation provider. The system should have a document sharing feature, but no customization is necessary as an off-the-shelf product should be sufficient. This is a new project, so no existing intranet system is in place. The ideal developer should have experience with setting up intranet systems from scratch or catering for the specific needs of supported accommodation providers. If you can help me out, please let me know!
