From there, he hopes to work with the WTC's junior committee to set up deals where players who find they like the sport will want to take part more seriously and sign up with the club.
"At the moment I'm just in recruiting mode," Baker said.
"All the [WTC] oldies say to me, 'we need more youngsters'.
"Our job now is go through the schools and find more kids."
Around six Whanganui schools have signed up for PROMAC to offer coaching to their students, with Baker estimating he and McNamara could meet with around 1500 juniors across the wider region.
"All our groups have doubled, just by ringing schools and getting the kids."
While the Wanganui representative team still holds the Christie Cup, it is accepted they will be lucky to get through another summer with the Central Districts team trophy still in their possession after the loss of Hourigan, Butters, Michael O'Callahan, and sisters Gabrielle and Dana Hiri among several others.
"If we got all those kids for Christie Cup, that's a pretty good team," said Baker.
The idea of their coaching programme is to find players who will want to make tennis their No1 sport so they focus on it for the full 12 months, not just picking it up every summer.
"You're trying to keep them in the game and hopefully by winter, they're still hitting balls down at the club."
McNamara will be bringing his Palmerston North group of elite youth players to Whanganui today for the start of the 2016 Open, and Baker said they have a goal of setting up a similar travelling group by combining players from the Feilding and Wanganui tennis clubs.
"That's what we want to have in Whanganui - a tournament team of kids."
