Bootstrap Service Portfolio Website

I need a clean, lightweight website built with plain HTML, CSS, vanilla JS, and the latest Bootstrap to showcase and promote my services. The layout should feel modern yet simple so visitors immediately understand what I offer and can contact me without friction.

Right now my logo is still being designed, so please set up a temporary placeholder and structure the header in a way that lets me swap in the final SVG or PNG by replacing a single file.

Deliverables
• Responsive landing page that highlights my core services and value proposition
• Portfolio section where I can add or remove individual project cards quickly (editing one HTML/JSON block is ideal)
• Fully working contact form with basic spam protection that emails enquiries straight to my inbox or routes through Formspree / similar

Code requirements
Bootstrap 5 only, no additional frameworks. Keep the markup semantic, comment key sections, and separate custom CSS and scripts into their own files so I can tweak colours and copy later. After completion, hand over either a zipped folder ready to upload or a GitHub Pages link where I can clone the repository.

Acceptance
When I can open index.html, see the portfolio grid render correctly on mobile and desktop, and receive a test message from the contact form, the project is done.
