    Our property, Mortons at Russell’s Bridge, needs a premium logo that feels as enduring as the land itself. The Morton Bay fig tree is the heart of the design—it’s the most recognisable feature on the farm and must take centre stage.

The finished mark should work flawlessly in black-and-white; any shading or texture you add has to translate cleanly to single-colour use for signage, embroidery and screen-printed merchandise. Because the logo will appear everywhere—from the gate sign to hats and feed bags—I’ll need fully scalable vector artwork and clear usage guidelines. Deliverables • Prim...

    ...then reveal the full page. • Once loaded, the layout stays fixed; visitors will not need to scroll at any breakpoint. Core content The page only has to display my garage name, a short tagline and room for me to add a phone number or email later. I already own the domain, so the finished files simply need to be drop-in ready for my host. Tech notes Lightweight HTML, CSS and a touch of JavaScript (or a small GSAP/Lottie snippet if you prefer) is fine—just keep assets lean so the load animation stays smooth. Deliverables • Fully responsive, non-scrolling single page (HTML/CSS/JS) • One concise loading animation integrated and tested • Clear instructions on where I can edit text or swap the logo in future If you’ve built similar fixed-v...

    I need a clean, responsive one-page site built in pure HTML, CSS (and a little vanilla JavaScript if you wish) that mirrors the overall layout and feel of the reference ZIP I will supply, without copying any assets. The text and images you will drop in come from me; your job is to recreate the structure, swap in my content, and keep the design lightweight and fast. Key sections to include on the single page: • About Us • Services • Contact Form – the form must validate, send submissions to a single company email, and show a friendly success/failure message. The site is strictly information-based, no e-commerce or CMS. When you are done, you’ll upload everything via the cPanel credentials I provide and make sure it sits live under our new domain. Please d...
