Hi Ota, 

could you provide an email to connect with us? We can have a sales engineer to chat with you about prices/plans. 

For your second question, after you bought our plan, you can create sub-account and assign those to other person. so other person don’t need to buy. Also, other person can use our standard client which is available on Mac, Windows, iOS, Android to join the meeting.
