resseling hosting

We provide support and maintenance to our clients WordPress. We already sell hosting as an add-on service (VPS with Cpanel or LightSail), but we'd like to offer wpmudev hosting services from now on.

We really would like to fully engage with WPMUDEV to provide a full service to our WordPress clients ( Service + Plugins + Hosting )

- My Questions:

1. What's the best way to resell the hosting service? ( we use whmcs today)
2. Can I give to my clients access to any kind of dashboard about their hosting?

Thanks in advance!
