WordPress Portfolio Carousel Setup

I’d like a simple, attractive portfolio section added to my existing business WordPress site so visitors can quickly browse examples of my work. All items will be image-based and should display in a smooth carousel/slider format that looks clean on both desktop and mobile.

Here’s what I need from you:
• Recommend and configure a reliable portfolio plugin—or build a lightweight custom solution—so the slider integrates seamlessly with my current theme.
• Upload a handful of sample images I’ll supply, making sure the layout, spacing, and navigation arrows/dots are consistent with the rest of the site’s styling.
• Keep page-load impact minimal and ensure the slider is fully responsive.
• Give me clear, step-by-step instructions (or a quick screen-share) so I can add, remove, or reorder projects in the future without touching code.

I’m working with a tight, fixed budget, so an efficient approach—leveraging an existing plugin or your own reusable code—is preferred. Once the carousel is live, tested across the major browsers, and I can update it myself, the project is done.
