Nonprofit Event Landing Page

I run a WordPress-based nonprofit site and we’re getting ready to announce a new fundraiser. I need a single, modern-and-clean landing page that folds seamlessly into our current theme and drives one main action: purchasing event tickets. Here’s what I’d like delivered: • Responsive design and build of the page, with the primary “Purchase Ticket” call-to-action wired to our existing Stripe account. • Additional Stripe checkout flows for Host packages and clearly presented sponsorship tiers and benefits so supporters can select and pay in one place. • A permanent QR code that links straight to this landing page; I should be able to place the code in print materials and know it never changes. • Proper routing from our site’s main “Events” page so visitors can move back and forth without feeling they’ve left the site. Everything needs to load quickly, look sharp on mobile, and preserve the accessibility standards already in place. Once you’re finished, hand off any custom templates, shortcodes, or instructions I’ll need for future edits.
