I need a Grant Writer for Canadian Tire JumpStart Program

We are a mixed martial arts and fitness center. We provide classes for kids in Boxing, Olympic Wrestling, Brazilian Jiu Jitsu, Muay Thai, Kickboxing and Self Defense.
We are in a community with lower income households and would like to a grant to provide these services to the kids in lower/challenged neighborhoods.
We need someone who understands these programs and how to ensure we qualify for the grant. This is our first time looking for a grant and have no previous experience
