The whole point of free software is that it can be modified to suit any user's potential requirements, so pretty much by definition, if you want point 3, your software isn't free.
Sounds like shareware. I can't point you to a license I would personally recommend, but Google has lots of results. See also http://en.wikipedia.org/wiki/Shareware

听起来像是共享软件。我无法向您指出我个人推荐的许可证，但 Google 有很多结果。另请参阅http://en.wikipedia.org/wiki/Shareware
