Hi there,
You want 2 pages or 3: Homepage, Pricing page and customization page?
what info you want to use on customization page?

I am not really after the website - Just the shop page that we will include into the existing website

Customisation page will be almost like [Non image link removed]page. When the user selects the pack - in this case a school it takes them to a calculator page.

ok thanks, I'll soon start working on it, and come up with the exact one you want.

I'll design that one, but you have to hire a more professional, expert to develop this site on Shopify.
You can use WordPress as a alternate with woo commerce plugin.
So whats your point: Shopify or WordPress?

Yeah understood. Happy to get a shopify developer. I prefer Shopify.
