Website Content Update Rescue

My new website went live recently, yet a few critical details still need polishing. I have the revised copy and fresh images ready to go, but I no longer have backend access and the original developer has vanished.

I need a web pro who can:
• regain or recreate secure admin access (via hosting panel, CMS reset, or a quick migration—whatever proves fastest and safest);
• swap in the new text and replace the specified images across the existing pages;
• double-check that layout, links and responsiveness remain intact after the edits.

The changes themselves are minimal—just a handful of text blocks and several image slots—but access is the immediate hurdle. Once you’re in, the updates should be quick. Please let me know your typical turnaround time and the CMS or hosting tools you’re comfortable with so we can get this resolved right away.
