Shopify Payment & Theme Tweaks

I’m preparing a new Shopify store for launch and need someone who can quickly make the payment flow production-ready while handling small, ongoing improvements.

For this first milestone I only need the essentials:
• Configure my selected theme so it’s fully responsive and ready to go live.
• Integrate the two initial gateways—credit-card processor and PayPal—then verify checkout, refunds, and transactional emails in both test and live modes.
• Keep the code clean (HTML, CSS, JavaScript, plus any lightweight PHP for external scripts) and leave a concise change log so the rest of the team can follow your work.

After launch, I’ll come back to you for regular feature updates such as adding new sections, so an eye for iterative releases and clear communication is important. If this sounds like your kind of project, let me know how you’d approach the setup and how soon you can deliver the first pass.
