Minimalist E-commerce Notes Website

I need a clean, modern-minimalist site where students can browse my handwritten Class 9 and Class 10 study notes, pay, and instantly receive a direct download link on the purchase-confirmation page. User-friendly navigation is my absolute priority; everything should feel effortless on both desktop and mobile.

Key pages will showcase colourful note previews, short descriptions, and clear pricing. After checkout (any reliable payment gateway is fine), the file should unlock automatically so there is no manual intervention from my side. I will use the URL in my Instagram bio, other socials, and my CV, so the design has to look premium yet load quickly.

Please tell me:
• The timeframe you need from kickoff to launch
• Your total development cost
• 2-3 live examples of similar work you have built

I’m flexible on the underlying stack—WordPress + WooCommerce, Shopify, or a lightweight custom build—as long as the result matches the style and functional flow described above.
