Hi, We already had a freelancer working on our WhatsApp marketing script and some add-ons are done on local server. Now we need someone to: Migrate & Setup: Deploy in AWS (no cPanel, only AWS panel). UI/UX Changes: Improve design, landing page edits, and overall flow look/feel. Chat Flow Builder: Like AI Sensy (drag & drop builder) where users create templates with multiple buttons, link each button to custom flows (e.g. Pricing → Talk to Sales → Main Menu). OTP & Automation: User registration with WhatsApp OTP verification + automated welcome messages. Click-to-WhatsApp Ads: Add features to support ad campaigns with integrated flows. Admin Panel: Manage pricing plans (e.g. ₹999 basic = 1000 contacts, 5 flows), add-ons, per-message pricing, checkout/cart system. Integrations: Multiple 3rd party integrations (Google Sheets, Zoho, Hubspot, etc.) that users can connect or download. Analytics: Google Analytics integration, campaign & per-message reporting. Meta API: Verification, testing & bulk messaging flow testing. Mobile App Setup: Basic Android/iOS app integration. We want the chat flow builder and add-on system to work very similar to AI Sensy. Please check their YouTube videos for reference. If you can take this forward, please share your timeline please note we need this in 1week and most of features from ai sensy also langing page changes
