HTML to Squarespace Conversion

I have a 6-page website built in HTML — Sport for Good, a social impact measurement platform for community sport. The site includes a homepage, calculator, consultancy, conference, about, and contact pages. All copy, design, and assets are complete and ready to hand over.

I need the site rebuilt in Squarespace (Business plan) with the design faithfully replicated.
The main technical requirement is a JavaScript social value calculator that needs to be embedded via Squarespace's custom code block. Everything else is standard content pages.

Deliverables:
— 6 pages rebuilt in Squarespace matching the HTML design
— JavaScript calculator embedded and fully functional
— Nav, footer, and typography consistent across all pages
— Basic CMS setup so I can edit copy myself after handover

Budget: £80—120. Looking for someone with Squarespace experience who can turn this around within a week. Please share relevant examples of previous Squarespace work with your proposal.
