Требуются операторы в call-center

We are the company wallpanels.com - we have recruiters who connect with candidates via WhatsApp, and it has been decided to move to a new level and create American accounts (with an American phone number). Therefore, the current task is as follows: To understand where we can buy +1 numbers (preferably with our area code), to determine whether we need business WhatsApp accounts or regular ones, and to hand them over for use. Importantly, we must retain access to all related platforms and accounts, we will cover the costs for using the platforms, and also, when collaborating with us, the contractor must sign an NDA and adhere to it.
