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 and cost.
