Ad Space Sales

I am looking for advertising space on t-shirts to be filled. The shirt will be produced in at least a 1,000 unit run. The advertising spaces will be 6 on the back of the shirt and one on the sleeve. The advertisements will be black ink on a white shirt. The asking price is $1 per unit ($1,000 cost to the advertiser for a 1,000 unit run). I will pay on a commission basis of 10% with a 1,000 unit minimum, and $1 price floor. If you can fill all 7 spots, you will receive $700 if the minimums are met. Each advertising spot on the shirt will have room for a graphic (logo), contact information (website, phone # etc.), as well as their sales pitch (some kind of % off, or a marketing phrase). If all spots are able to be filled, then higher quantities are available ( up to 10,000 shirts). There will be approximately 50,000 people at the event where these shirts will be handed out for free within Washington State.
