Hello Manashe,
Thanks for reaching out. I'd be more than willing to chat if you'd like to reach out to me directly. We have both the Open Source product and the Partner version of Kazoo which we can go over so you can choose the best path moving forward. We also are having a training her in SF at the SF Code Beamer Conference which is geared towards building apps on Kazoo March 4th-5th, 2019. For more detailed information on this you can go to: https://www.eventbrite.com/e/code-beam-sf-2019-tickets-43197815830?discount=Kazoo10 Once you go there, click on the tickets button and scroll down to the tickets that say, "Training Course: KAZOO" and you can purchase your tickets if interested.
