I have already purchased the WhatsMarkSaaS script from CodeCanyon and need it fully deployed on my dedicated server. The stack is straightforward—Ubuntu with an empty MySQL database ready for use—and my official WhatsApp Business API account is live. Here’s what I need you to handle end-to-end: • Install the script, upload all files, and set the correct folder permissions. • Configure the .env file with database, mail, queue, and license details so the app boots without errors. • Point the platform to my existing MySQL instance and run all migrations/seeders. • Connect the software to my official WhatsApp Business API number so bots, bulk sender, message templates, and live chat modules work. • Verify webhooks, callbacks, and cron jobs so scheduled and automated campaigns trigger on time. • Apply basic hardening—SSL check, firewall rules for the relevant ports, and a quick security audit of writable directories. • Provide a short hand-off document covering login URLs, admin credentials, and how to update environment variables. I’ll supply the license key, server SSH access, and WhatsApp API credentials the moment we start. A clean, error-free launch plus a brief walkthrough call will mark the project complete.
