WordPress Age Gate & Checkout Tweaks

I’m looking to tidy up a few key user-experience points on my WooCommerce site. First, every new visitor must pass a 21+ age gate that appears as a pop-up when the site loads. If someone clicks “I’m under 21,” they should be taken straight to a simple “You must be 21 or older” page and barred from browsing further. Second, I’d like the major credit-card logos displayed consistently in the footer, on every product page, and again on the checkout screen so shoppers instantly know their payment options. Finally, before any payment is processed I want an Order Review page inserted—essentially a final summary step that lets customers double-check items, quantities, totals, and shipping details before they commit. Deliverables • Age-verification pop-up with under-21 redirect • “You must be 21 or older” landing page • Credit-card icon placement in footer, product pages, and checkout • Order Review step added just prior to payment submission The site runs on the latest WordPress + WooCommerce stack, so you’ll need solid PHP, JS, and CSS skills to implement and style these features cleanly without breaking existing functionality. Let me know your timeline and any plugin or custom-code approach you prefer so we can get started right away.
