You might try lawdepot.com for some blanket agreement. Maybe guru.com or rentacoder.com or one of those other sites will have some standard engagement agreement.

Probably cost a few $$ on lawdepot.com to get what you need -- I didn't see anything that specifically addressed what you wanted. Some of the open source licenses might have resources that they point to: opensource.org might be a starting point, but that is more a license agreement for software you have produced.
