I need a single, well-structured “Contact Us” page that represents my business online. The stack is fixed—plain HTML5 templated with Bootstrap, front-end validation in JavaScript, and a small PHP script that writes every submission into a MySQL table and fires an email notification. Please make the layout fully responsive, keep the markup clean, and respect Bootstrap’s utility classes so I can expand the site later (Home or About pages could follow). Deliverables • Responsive Contact Us page (Bootstrap 5) • PHP handler with server-side validation and reCAPTCHA v3 ready hook • MySQL table script + brief README explaining setup • Simple success/fail messaging wired to the front end Once everything is working on your end, hand over the code and a step-by-step deployment note; I’ll replicate it on my host to sign it off.
