I currently have an open source project that is licensed under GPLv3.  I'd like to dual license it, so I can offer it for commercial use.  Are there any resources for choosing or creating a commercial software license?
I think Binpress' license generator is excellent:

Adjust the options below to fit your business needs.
Once you hit "Generate License" at the bottom, you will be given a unique address to your generated license.
If you leave an Email address and name, you can edit your license at any time (optional).
