Convert website from Web Self Storage to Storedge management software -- 2

A website for a self-storage company is in need of long-term maintenance, support and upgrades. Budget is $500-$1,000 per month. The site is built in React, HTML/CSS as two apps: a client and a server. The server app integrates with the WSS (Website Self Storage) reservation booking & management API. There is an issue with WSS that is preventing booking that needs a solution in the short-term. In the near future, the entire booking system needs to be migrated to Storedge, a WSS competitor. Both apps are hosted on Heroku with repo and documentation on Gitlab. Also open to redevelopment of the project with native Storedge integration. https://valueselfstorage.net
