Finish My Service E-Commerce Site

I already have a good portion of the codebase in place—layouts, basic styling, and the skeleton for a shopping-cart flow—but the site is not yet production-ready. I’m looking for a developer who can take what I’ve written, clean it up where necessary, and turn it into a fully functioning e-commerce platform focused on selling professional services.

Here’s what I need from you:
• Audit my existing front- and back-end files, identify gaps or conflicts, and propose fixes.
• Wire the code into a smooth service-purchase flow, from selecting a service through checkout confirmation.
• Ensure the site is responsive and loads quickly on both desktop and mobile.
• Configure secure user accounts and order tracking so clients can log in and review past purchases.
• Set up and test payment processing (I’m open to Stripe, PayPal, or a comparable gateway—whichever integrates most cleanly with the current stack).
• Deploy the finished site to my preferred host and walk me through any environment variables or config files I’ll need to maintain.

Acceptance criteria: the site goes live without console errors, services can be purchased end-to-end, and I can reproduce the deployment steps on my own machine.

If you’re comfortable jumping into an existing codebase and can turn it into a polished, reliable service-commerce site, I’d love to hear how you’d approach this and how soon you can start.
