I’m looking for a web-development expert to integrate a fully functional contact form into my existing website. The project is strictly a feature addition—no redesign is needed—so your work should blend seamlessly with the current layout and styling.

Here’s what I expect:
• A responsive contact form that captures name, email, subject, and message fields, plus any anti-spam measure (reCAPTCHA or similar).
• Server-side processing that safely validates and sanitises inputs, then sends the message to my designated email address.
• A confirmation/thank-you message for users and an error state for failed submissions.
• Clear instructions or light documentation so I can adjust destination email addresses later if necessary.

Tech flexibility: feel free to work in PHP, Node, Python, or another mainstream stack as long as it integrates smoothly with the current codebase. I’ll provide site access and a quick walkthrough as soon as we start.

Please share a concise plan—languages, libraries, timeline—and one or two live examples of contact forms you’ve built. I aim for a reliable, professional result and I’m ready to give prompt feedback throughout the process.
