Car artwork for X number garments bearing the image (downtown Los Angeles)

You make shirts, purses, etc.
and could use some exotic car artwork? I am a fine artist with over 50 paintings of cars, mostly exotic.
Will trade your use of one of my images in trade for X number of your clothing items using the art.
Say you get unlimited use of one of my Ferrari paintings in exchange for 50 T-shirts.
Lower price if the reproduced image bears my signature.
Even lower yet if you include my email address at the bottom.
Since I sold my paintings for as high as $1000, this is a great deal.
The pictures showing the prints on garments are samples--I never mass produced them.
So let's do one item and see if this works out.
