Simple Contact Form REST API — Java / Spring Boot (Small Fixed-Price Project)

I need a Java developer to build a small, clean REST API for my business website's contact form (ArchTech Solution — a software services company). Scope of Work (small & clearly defined): One REST API endpoint built with Java + Spring Boot Accepts contact form submissions: name, email, phone, message Input validation and proper error handling Saves submissions to a database (MySQL or any simple option) Sends an email notification to my business email on each new submission Basic CORS setup so my static website frontend can call the API Deliverables: Complete source code (clean and well-structured) Short instructions on how to run/deploy it A quick test (Postman collection or sample request) Budget & Notes: This is a fixed-price $20 project with a small, clear scope — no scope creep, I respect your time. I will leave an honest 5-star review for quality work — a good opportunity if you're building your Upwork profile. If the quality is good, I have more backend work planned for future projects and would prefer to continue with the same developer long-term. Estimated effort: 2–4 hours for an experienced Spring Boot developer. Please mention your delivery timeline when applying.
