Cox has plenty of experience of that, having created the GT Academy programme that took 23 people from gaming to the racetrack with Nissan.
"The big prize for the gamers in GT Academy was one race ... this time we're saying we're confident we'll find someone who's good enough and who will do a full season in Aston Martins at the biggest tracks in the world."
The winner from 10 finalists - eight of them champions from top motor racing esports series and two separate qualifiers - will become a professional racing driver with Swiss-based R Motorsport, who work closely with Aston Martin.
Van Buren will also be racing a full season as team mate to the winner. Cox said the prize of a full season was worth more than $1 million (roughly R14.1m).
The circuits will include Monza, Le Castellet, Brands Hatch, Nurburgring, as well as 24-Hour endurance races at Spa-Francorchamps and Daytona.
Montoya, who won seven Formula One grands prix with Williams and McLaren, is also a keen online racer and still practises on simulators.
Cox said he had started talking to the outspoken Colombian about gaming when they met at Daytona a year ago and he was "fully up for it".
"I know the skills between real and virtual are completely transferable, so my job on WFG is to make sure these gamers are hungry and perform under the pressure I intend to put them under," Montoya said.
