I'm the maintainer/main contributor to a Java library, that is open source software under BSD license. I currently receive no funding for my work in this project, but demand is rising. As a full time employee, and a father I don't have a lot of spare time to put in. But there are possible clients who are willing to pay for fixing bugs or new features, and my current employer is positive to let me do this.
My question is, where can I find a good (template) contract to use for short-term OSS work like described above, between me/my employer and the third party (client)?
I have searched extensively, but I find only template contracts for use between an employer and me, to allow me to contribute to OSS. I have this covered, and this is not what I am looking for.
