<p>Nick, you need to get this agreement on paper, ASAP.</p>
<p>You also need to make this a "limited use" license agreement. Believe me, it's better to be safe than very sorry later. The limited use agreement is a contract where you specify ALL the terms, and make clear (very clear) they cannot use your photographs or any derivatives of your work for any other reason.<br>
If you just say "OK, 50 or 60 T shirts sounds good, you make it easy to tempt them to send the file off the Vista prints and print off 2000 4x6 post cards or 500 5x7 greeting cards.<br>
Your on the right track by stating you would need to re-negotiate if they decide to print more than 60 t-shirts, yes that is appropriate and common. However you NEED-NEED-NEED to state your agreement is very limited to a specific number and not to be used for any other purpose.</p>
