Setup Large WhatsApp Support Groups

I have a clean list of 10,000+ customer numbers that need to be gathered into well-structured WhatsApp groups dedicated to customer support. The goal is to make it easy for people to ask questions, request “any WhatsApp file work,” and receive help quickly while giving me a channel to share occasional promotional videos.

Here is what I need you to handle from start to finish:
• Create enough groups to accommodate every contact without hitting WhatsApp’s participant limits.
• Import and organise all numbers, making sure each person is successfully added.
• Configure names, icons, descriptions and basic guidelines so members immediately recognise the purpose (customer support first, promotions second).
• Give me full admin rights to every group and hand over invite links once setup is complete.
• Test that large video files post correctly and are viewable to every participant.

Acceptance criteria
1. All contacts are added (or reported if a number cannot be joined).
2. Groups stay within WhatsApp’s limits and remain accessible.
3. I receive a concise hand-over document: group links, participant counts, and any numbers that failed to join.

You are free to use any automation or manual method that complies with WhatsApp’s policies, as long as you deliver the groups ready for immediate use. Let me know how soon you can start and how long you expect the full rollout to take.
