wordpress/javaScript Developer Needed

Hi, I'm looking for an experienced JavaScript/PayPal developer to urgently complete an existing PWA checkout flow. The PayPal Smart Buttons integration is already working, but I need someone to implement the post-payment workflow, including capturing customer details, sending customer and admin confirmation emails, and ensuring the entire checkout process works end-to-end. The project is built with vanilla JavaScript (single HTML/PWA). The deadline is **Tomorrow evening**, so please only apply if you're confident you can deliver on time. If you've worked on similar PayPal checkout systems before, I'd love to hear from you.
