Optimise Existing Squarespace Sales Page for Mobile

I’m looking for a Squarespace developer/CSS specialist to optimise an existing membership sales page for mobile and tablet.

www.digitalpatternlibrary.com/membership

The page itself is already designed and built, and I’m happy with the overall design, branding, copy and desktop layout. I am not looking for a redesign or a new sales page.

The issue is that several elements that work well on desktop are not translating particularly well to mobile, especially large image/banner sections, spacing, image crops and some of the responsive typography/layout.

The page includes a mixture of native Squarespace blocks and custom code

I’d like someone to:
- Review the full page on desktop, tablet and mobile
- Optimise the mobile layout without unnecessarily changing the desktop design
- Improve responsive image positioning/cropping, particularly banner/background images
- Ensure text remains readable over imagery at smaller screen sizes
- Refine mobile typography, spacing, section heights and buttons
- Make stacked sections and graphics feel intentional rather than simply compressed from desktop
- Check pricing cards, testimonials, feature sections and FAQs at common breakpoints
- Identify and tidy any existing CSS/code that is causing responsive issues
- Use clean, properly scoped CSS so changes do not unexpectedly affect other pages on the website
- Test the finished page across common desktop, tablet and mobile widths

This is an optimisation job, not a redesign.

I have spent considerable time developing the page and its visual hierarchy, so I’m specifically looking for someone who can take an existing Squarespace design and make the responsive implementation feel polished.
I’d also like any custom CSS/code used to be left reasonably organised/commented so I can understand what has been changed in future and make reasonable changes and updates myself.

The website is live, so I’d ideally like someone comfortable working carefully on an existing Squarespace site without disrupting other pages.

When applying please send:
1. Examples of Squarespace sites/pages you have personally worked on, particularly responsive/mobile optimisation.
2. A brief explanation of how you would approach this project.
3. Your estimated cost and turnaround time.
4. Confirmation that you’re comfortable working with custom CSS and responsive breakpoints, rather than relying solely on Squarespace’s built-in mobile layout.

Please review the existing page before quoting.
This is an optimisation project, not a redesign. Please do not send proposals for a complete website redesign.
