Professional SharePoint Site Development

I need a corporate SharePoint site for our 30-member service business. The site will serve as a centralized hub for our team, featuring:

- Home page with:
- Buttons/Pages for:
- Files/Documents/Links Sharing
- 'News' Items/Staff Announcements (Company Updates, Employee Achievements, Upcoming Events)
- 'Key Contacts' (Internal)

- Simplified integration with our existing OneDrive, including:
- Automatic file synchronization
- File sharing and collaboration
- Version control

- 2-3 Separate Pages with Controlled Access:
- Admin Page (Admin Team Members Only)
- Techs Page (Field Techs Only)

Ideal Skills & Experience:

- User Access Control Setup

Looking forward to your proposals!
