Commission-only: sell ad space in my free racing game

Commission-only sales rep wanted to sell ad space inside my free one-thumb racing game, Drift Daily (free in the browser at driftdaily.duallink.link, new track every day). Ad slots: the start gantry, roadside boards, flags and the "today's track presented by" sponsor slot. Every player sees the brand's logo on every run. Your job: find brands that target 20 to 30 year olds (energy drinks, car accessories, apps, sportswear) and close deals for single campaigns or monthly packages. Pay: 30% of every deal you bring in, paid through Freelancer milestones after the brand pays. No fixed fee. The game is new and the audience is still growing, so this suits someone who already has brand contacts. I provide the rate card, the slot mock-ups and live player numbers. To apply, tell me which brands you can reach and one past ad or sponsorship deal you closed.
