I need a one-page website replicating on Squarespace

We're buying a business, due to complete on 1 July (therefore the absolute deadline for this task) and it comes with a website. The site isn't currently built on Squarespace but we'd like it to be, so that we can make changes to it ourselves without bothering our SEO people who would otherwise be the ones we'd ask.

I can't give the domain of the site out at this stage as it's confidential until completion - but of course I will supply this to whomever I end up working with. For now, I asked Grok to summarise the site, for your information:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Word count target:
Approximately 650-750 words of main body copy (excluding headings, CTAs, and testimonials).
The content is straightforward, professional, and benefit-focused, with a warm, approachable tone.
Number of graphics:
Very low — likely 2-4 total visual elements (including logo).
The site is extremely minimalistic and text-heavy.

KEY STRUCTURAL FACTS

- Homepage layout: Single long-scrolling page (one-page site structure). No complex multi-page navigation.
- Header/Navigation: Simple top header with business name/logo and basic menu (Home, Services, About, Contact). - Clean design with no mega-menus or dropdowns.
- Hero Section: Prominent headline with a subheadline and clear "Get in Touch" call-to-action button. Minimal or no background image.

MAIN SECTIONS (in order)

- About / Introduction

- Company overview, years in business, family-run background, local focus, and range of clients from sole traders to larger companies.

- Services
Broken into 3-4 clear subsections with short descriptions and bullet lists:
New Business Support (setup guidance, registrations)
Regular / Ongoing Accounting Tasks (payroll, VAT, accounts preparation, etc.)

- Additional Services (self-assessment, registered office, specialist reviews)

- Testimonials
Section titled "What our customers think" — 3-4 short quotes with client names / business types.
Contact
Includes contact form, phone numbers, full address, and privacy note.

- Footer: Basic contact info plus links to Privacy and Cookies policies.
- - - - - - - - - - - - - - - - - - - -

I don't know how clear the above makes it! But we don't need anything spectacular in terms of SEO or anything - and images etc can be lifted from the original site. When whoever does this job is doing it, they will be able to basically (which is what we need) copy it.

For context, I (an accountant with no creativity or web design skill) would be able to do this on Squarespace in probably half a day, so hopefully what I'm asking for is nice and simple for someone who uses it anyway.

As always when I post a job on here, the budget is purely to be able to submit the job - it has no relation to what I'm expecting to pay (which may be higher or lower!).

Thanks
