WordPress/WooCommerce Site Maintenance — Ongoing Monthly Retainer (Art Ecommerce Site)

I run an online artist Gallery, a live WooCommerce store selling original artwork, prints, and framing. I'm looking for an ongoing monthly maintenance arrangement to keep the site secure, up to date, and running fast — not new feature development or content work, just solid technical upkeep. Part time job to keep it running fast. What's covered on the site: WordPress core, theme, and plugin updates, tested before applying Security: firewall, malware scanning, login hardening, brute-force protection Daily backups with off-site retention and a tested restore process Uptime and SSL monitoring Database optimization and ongoing performance/speed checks — this is the priority, since the site is image- and content-heavy and needs to load fast every day Occasional break-fix support if something goes wrong What's NOT needed: Content uploads, product listings, or pricing changes — I handle all of that myself New features, redesigns, or major dev work (would be scoped and quoted separately if it ever comes up) Good to know: the store also connects to a separate custom-built AWS platform (a personalization/editor tool) via a custom plugin, built by another developer. You won't need to maintain that platform, but updates on the WordPress side need to be checked so that connection keeps working without breaking. This is meant to be an ongoing relationship — I'd rather find someone reliable to keep this running month to month than repeatedly hire for one-off fixes. Budget: Open — please quote your monthly retainer rate (or hourly, if you prefer) for the scope above, so I can compare a few options.
