Stafford Paedophile Anthony Bayliss, aged 77, was regularly using escort services at the time, driving around Birmingham in his Rolls Royce and claiming to be a successful TV producer.
He met the victim when she was 14 and went on to rape her on two occasions at his home address.
The Crown Prosecution Service (CPS) said Anthony Bayliss and Birmingham Paedophile Paul Doyle, aged 64, were convicted of sexual offences relating to two girls more than 20 years ago.
The two victims in the historic case were aged just 14 and 15 when the offending began and both were living in the care system.
The offences happened between September 1996 and December 1997 when Paul Doyle ran a kissogram and an escort agency from a taxi base in Digbeth in Birmingham city centre.
Paul Doyle was convicted of living on the earnings of one of the victims who began working for his agency when she was 14 or 15. Although she received a wage, the money she earned was given straight to him.
Jurors heard how he would insist that the women and girls who worked for his agency have sex with him as an initiation. He was convicted of indecently assaulting the second victim.
Paul Doyle, of Birmingham, and Anthony Bayliss were prosecuted by the Organised Child Sexual Abuse Unit of the CPS following an investigation by West Midlands Police.
Specialist prosecutor Claire Brinton said: “The victims in this case were vulnerable children who had their innocence cruelly stolen by adults who exploited them for sex and money. Anthony Bayliss and Paul Doyle targeted their victims because they were young. This enabled the defendants to exploit them for their own sexual gratification and financial gain.
“We would like to extend our thanks to the victims who showed extraordinary bravery in reporting what Anthony Bayliss and Paul Doyle did to them. I hope they can find some comfort in knowing that it is because of their evidence, that we have been able to bring these offenders to justice.
“The CPS remains dedicated to pursuing justice for victims of child sexual abuse and will continue to work tirelessly to hold violent sex offenders accountable – no matter how much time has passed since they committed their crimes.”
Supt Wes Martin, of West Midlands Police, said the force took reports of sexual attacks “extremely seriously” despite the passage of time.
He said: “These were deplorable and inexcusable crimes where vulnerable young girls were trafficked into the West Midlands and sexually exploited. Paul Doyle offered the girls for sex while Bayliss paid for sex with an underage girl.”
“We will always seek to ensure perpetrators are brought to justice for their vile actions,” he added.
Following a trial at Birmingham Crown Court Paul Doyle was found guilty of one count of living on prostitution and one count of indecent assault. Anthony Bayliss was found guilty of two counts of rape. They will be sentenced in April.
