Affiliate Marketing Secrets

Hi All,
Can someone suggest me, some of the current niche it skills, that have high billing rates.
Regards,

I’m taking over as manager for my twin nieces; two adorably precocious 11 yr olds who rap. Billing themselves as Twitter Dum and Diddle D, the two have barnstormed the juicebox circuit and dolly stomped their way through daycare appearances, and are setting their sights on global recognition.
They want to get viral on YouTube, with their remix of “Spankin'”, from their original “Scribbled” mixtape.
Twitter Dum suggests posting her lyrics online, in serial tweets, while DIddle D collaborates with the gurus at Xylophone Tone Def Dubbers, to hash out the beats and melody.
No doubt, these two little girls are at the top of their game right now, and Twitter Dum thinks the lyrics leak would be just the move to help them carve a niche in the Jibba Rap genre.
Do you think its wise to let them post lyrics before publishing? Should they break out with new mixes before tossing these little pearls of wisdom before the communal swine? I tell them they are setting themselves up to have their lolli’s taken….what say you?
