Wialon Hosting and Wialon Local purchase

Hello friends.
I am a seller of GPS tracking devices. I just met Wialon. I want to integrate devices into Wialon. Can you explain to me? In Wialon Hosting, the Dealer price and the price of Wialon Local are determined by the Sellers (Wialon Partners) themselves? Or are these prices fixed and determined by Gurtam? I could not agree with Wialon partners in my country. Can you please suggest me a reliable reseller where I can buy Wialon Hosting and Wialon Local?
