Create and Set up meta for developers account for whatsapp business API

I am looking for an experienced Freelancer to help set up and manage a meta developer account for my WhatsApp Business API. I'd like to integrate the API with a website. After setup, I'm not sure if I need assistance with ongoing account management. Therefore, I am seeking someone who will be able to work efficiently and create a successful integration between the API and the website. I require a Freelancer who has experience with setting up meta accounts, integrations, and is able to provide continuing assistance with account management if needed. If you have experience with both website and mobile app integration and management, that would also be preferred. If you think you are the right fit for this project, please reach out and let us know your thoughts.

The most IMPORTANT thing to take in consideration is that the messages will be only notifications not ads or promotion so i need to save costs as much as i can since I'm not providing the notifications service in return of money
