Fix Price Display & Location

My site is mis-reporting key figures: product prices and inventory counts show the wrong values on catalogue and checkout pages. The data exists correctly in the database, yet what visitors see is inconsistent. I need a developer who can track down the root cause—whether it’s the database query, server-side logic, or a front-end caching/script issue—and ensure the numbers render accurately every time the page loads or stock changes.

Once that is stable, I also want a straightforward location feature added so customers can identify their nearest store or pick-up point directly from the site.

Deliverables:
• Correct, real-time display of all product prices and inventory counts
• Integration of the new location lookup/selector, styled to match the existing UI
• Brief change log and hand-over notes so I can maintain these fixes going forward

Please tell me which framework or language you intend to use, and when you can start.
