Dual Currency Checkout Upgrade

My WooCommerce shop is live and stable, yet the checkout page could look sharper and, more importantly, it must now accept both US Dollars and Pesos Argentinos.

Here is what I need done:
• Redesign the checkout so it feels modern, clean, and fully aligned with the rest of the site’s branding. I’m open to your creative input on layout, typography, and micro-interactions as long as the flow stays simple for the shopper.
• Set up PayPal to process Dollar payments and MercadoPago to handle Peso transactions.
• Let shoppers actively pick their currency from a clear selector; no auto-detection—choice is key.

Please make sure all totals, taxes, coupons, and order emails display the correct currency symbol and formatting. Test purchases in both currencies should pass end-to-end before we wrap up.

If you have recent WooCommerce dual-currency examples, I’d love to see them.
