You might find useful a book I used to prepare various documents for situations you might find yourself in as your career blooms! It is called
Business and Legal Forms for Fine Artists, pub. by Allworth Press, New York. It has copies of all sorts of contracts, and a CD to create the forms on your computer. I found a few of them useful, but modified them considerably to fit my own needs. They're pretty wordy, but you might like to check them out. Sometimes they address issues you wouldn't have thought of in writing up your own contracts. Good luck to you!
