This sounds like a very interesting project that I would like to work on, but unfortunately the payment is not guaranteed. Making the payment guaranteed will draw higher quality designers giving you a better chance at receiving more quality submissions. If you decide to guarantee the payment please let me know.

Do you just want the slogan on the tshirt? Or slogan and business name? If both, which one on which side?

of course payment is guarantee if I like the design.

only the slogan on the back of the shirt. thanks.
