This is an interesting case study, OP. Some people might be out of a job if it works
People asking 1500/1000 dollars are right to do so, because it will be around 500 dollars just to get everything you need for this job and after that its all about HARD WORK ! Believe me, when I say this, creating accounts, is hard. Pictures, Bios, Locations, etc.
But as soon as my accounts will get enough followers around 3000-5000, not only I will get GREAT advertising from all the accounts BUT Twitter might actually verify me.
Some people might say, it`s not enough, reporting them dont solve anything, etc.
YOU NEED to pass a SINGER, since now a days singers activate on YouTube its much easier for small to medium singers to get verified w/o a a label or something like that.
I know some POP band here that got verified with this method, its just that they dont want to admit it when I asked them, because they are nobody, I know them in real life and no one listens to them.
And they managed to do it without a contract or powerful PR people to talk to Twitter.
All they had was 30 Twitter accounts and 15 K followers, dont know how many of them are fake.
