Don't go with a master reseller if you're just starting out. Or pretty much ever.
Agreed. I myself am generally against those "master resellers", "alpha resellers", etc due the problems and issues I see all the time that arises, especially because they are using a custom plugin and not an actual system within WHM.
You should consider a proper reseller hosting provider which is providing genuine services and support as you are starting host , you will need to be very careful with the quality of your services and the support. So choose the right thing.
