I am a behavioral consultant and course provider looking to rebuild my professional website and digital infrastructure. My activity is already established, and I am now developing a new structured and scalable platform to support consulting services and online training. This is a medium-sized project (multi-month potential collaboration) and I am looking for a reliable long-term technical partner. The website should: Be built on WordPress (scalable and future-proof) Initially be in Italian, with structured expansion for English and future languages Allow different course offerings and pricing per language Support consulting services and webinar registrations Integrate secure payments and automated invoicing Be compliant with EU and Swiss data protection regulations Include full branding development (logo + visual identity) Core Functionalities 1. Multilingual Structure Italian as initial language English version with potentially different structure Architecture prepared for future languages (e.g., Chinese) Courses may differ by language 2. Courses & Webinars Live Zoom-based courses Free and paid webinar registration Automated registration confirmation and reminder emails Stripe payment integration Basic secure user area (Phase 1) Automatic PDF certificate generation after course completion No full LMS required at this stage. 3. User Registration & Secure Data Handling Email/password user registration B2C and B2B purchase flows ID document upload (admin-only access) Encrypted storage EU VAT validation (VIES) for B2B reverse charge 4. Automated Invoicing Progressive invoice numbering Compliance with EU and Swiss regulations Integration with an external invoicing system (e.g., Zoho Invoice preferred) 5. Email Marketing & Automation To be built from scratch. 6. Compliance & Security GDPR compliance Swiss data protection compliance Cookie consent system Secure hosting setup Data retention policy implementation 8. Ownership Requirements All accounts must be fully owned and controlled by me: Domain Hosting WordPress admin Stripe account Email marketing platform Invoicing system No proprietary lock-in solutions. What I’m Looking For Clear technical proposal Realistic timeline Detailed cost breakdown Examples of similar WordPress-based projects Experience with secure data handling and EU VAT logic
