Deploy PHP Site on Hostinger

I already have every file for my PHP-based website (HTML, CSS, JS, PHP, db.php, bookappointment.php) sitting on my computer; what I’m missing is a smooth launch on my Hostinger Premium Web Hosting account. My biggest worry is running into database connection problems, so I need someone who knows Hostinger’s control panel inside out.

Here’s what needs to happen:
• Upload all site files into public_html.
• Create (or locate, if it already exists—I’m honestly not sure) a fresh MySQL database, import the data, and generate working credentials.
• Update db.php so the new credentials are wired correctly.
• Fix any blank-page errors or warnings that crop up.
• Verify the contact / appointment form submits and stores data without hiccups.
• Hand back a fully live site that loads quickly on my domain.

Once we agree, I’ll send the hosting login and the zipped project. I’d like this wrapped up promptly and at a sensible price. If you’ve deployed PHP-MySQL sites on Hostinger before, especially ones with forms, that’s exactly the experience I’m after.
