I thought this was a pretty interesting read on Kizzo, one of the producers she's working with
Tearce 'Kizzo' Keaz is an explosive new talent who at just 24 is already snapping at the heels of global superstardom. He's a producer who stands out from the crowd with his ability to focus in on the minutiae of current trends and his roaring inferno of pure ambition that threatens to scorch anyone who stands in his way.
Every would-be superstar needs a great mentor to keep them grounded and help him navigate the rocky waters of fame. Kizzo was fortunate enough to be guided by several, including Niels Walboomers, who signed him to a publishing deal when Kizzo was just 18. Later, Kizzo had the good fortune of obtaining representation by DME Entertainment in the United States after being introduced to the well-known entertainment attorney and manager, David M. Ehrlich, who, because of his experience in working with producers, was a natural fit. Tony Scott, Johan't Hart, Mitch Crown and Örjan Graafmans all had a hand in tutoring this young star. The result is a maturity and an understanding of the business of music that belies his young years.
His influences include artists from the urban music canon, performers like Run DMC, Stevie Wonder, Herbie Hancock, Timbaland, Quincy Jones and Alicia Keys. However, what is perhaps most revealing is his unwavering respects for the likes of Bryan-Michael Cox, Danjahandz and Darkchild. For anyone remotely connected with the music business these are the industry's true celebrities. Producers of the biggest records for the biggest stars (think Lady Gaga, Beyonce, Justin Timberlake or Mary J Blige) are hit-makers first and foremost. Kizzo has the talent, the work ethic and the team to do the same.

Like I said before, I'm not expecting her to set the music world on fire or anything, but I think 200-300k is a pretty reasonable guess. She's still a pretty big name, and with a good first single and a decent amount of promotion, her sales should be fine.
