Most people who end up reselling did not set out to. They switched their own house over, then a brother-in-law asked, then two people at work, and at some point handing out favours turned into something worth charging for. This is the route for that.
What it used to involve - renting servers, chasing feeds, being woken at midnight because a stream had died - none of that reaches you. Credits are bought up front, the panel opens, and a customer account takes roughly fifteen seconds to create. Each one is a complete subscription in the standard Xtream format, so whoever you sell to can run whatever player they prefer and follow the same walkthroughs published on this site.
