I'm looking to set up a whatsapp business messaging and notifications for my clients, here are the requirements needed to be set up

1- We dont have a whatsapp business yet and need help with getting a package
2- Whatsapp will be used to send shipping notifications to customers
3- it will be used to send customers their order details with warranty documents and instructions.
4- Customers to contact us on whatsapp using a QR code that we send with the shipment asking for help with their products.
5- setting up a smart chatGPT with whatsapp business messaging to give quick answers to customers about troubleshooting of their products.
6- help getting ChatGPT educated on our products and troubleshooting instructions in a very human way.

Please let me know if you can help setting all the above.
