API Integration of an MVNO provider to build a Reseller\'s platform website

Hi, We need someone / or a team. Who can create a Reseller\'s portal for SIM activation and management for us. We accrue white label sims from an ISP and resell them along with our IoT devices. What we want is to create a platform where we can assign a lot of sims to a reseller, who can further manage the activation, recharge, disconnection, etc of the SIM We have access to the management portal of the SIMs we get from the MVNO and we also have access to their API stack which we can consume to build our own reseller platform. We would like to build this as a Wordpress Plugin, but we are open to suggestions. More details and API docs etc on messenger.
