NewSelf.com Clone with Checkout

I need an exact, responsive replica of newself.com built inside Webflow. The layout, animations, and overall flow should match the original, but I also want three new elements integrated seamlessly into the build:

• A simple checkout powered by basic payment processing and a guest-checkout path so visitors can purchase without creating an account.
• A short pre-screening questionnaire that uses multiple-choice questions to collect key details before people reach the payment page.
• A clean FAQ section styled to fit the site’s existing design language.

Hand the finished project over to me inside my Webflow workspace, with all pages, collection lists, and symbols clearly named so it’s easy for me to update text or swap imagery later. The finished site must load quickly, work flawlessly across desktop and mobile, and be ready for me to connect my own payment gateway credentials on launch day.
