Setup Document Template Using Power automate

We have a template document which according the entering in certain data like Company Name, Brand JPEG, selecting certain statements will generate a final word document to a set format. We use MS365 so can the freelancer create a template using power automate (or any other process within the MS365 suite) that we can use on our sharepoint to generate these documents.
An example template is attached.

Please guide me on what access you need to create this templating.

We have other 'reporting templates' to create so more follow on work to come
