React/Next.js Website Updates

I am looking for potential help / extra capacity to execute basic updates to Client websites that are built on React/Next.js. This includes things like content edits, new page publishing, banner/promo swaps, image and copy changes, store detail updates, redirect and SEO field fixes. Rough Definition: an update is a discrete task, typically under an hour; anything larger is quoted as "Dev" work. We're hoping to find an agency that we can partner with for "Always On" monitoring of client sites, and handling these update requests, while we continue to build out our theme functionality for the industry. We do a lot of work in the cannabis industry, so experience with that is a plus.
