WordPress Developer for One-Page Website

We need an experienced WordPress developer to build a clean, modern one-page website for a professional services project. The site should clearly present our services, include a Contact Us form with name, email, and message fields, and work well on desktop and mobile. It should also be easy for us to update later, connect to our existing domain, and include basic SSL and privacy/cookie consent setup where required. We already have the domain and will provide website text, services, and general design direction. Please share examples of similar one-page websites you have built, include your estimated delivery time, proposed fixed price and confirm what is included in your price. This is a small initial project with potential for future expansion.
