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?

This question appears to be off-topic. The users who voted to close gave this specific reason:

I think Binpress' commercial license generator is excellent: http://www.binpress.com/license/generator
How it works
- 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).
- To learn more about licensing options, visit our handy licensing guide...
Original answer refers to non working website. Here is working alternative https://eulatemplate.com/ which allows you to generate your customized
EULA license based on pre-existing licenses from selected companies.
I think most people just copy the EUA from some big software package from a big scary company.
Remember to replace Microsoft/Orace/whoever with your own name! There was the case of a database+programming language tools company big in the 90s that famously forgot!
What you want is a free software license without copyleft?
Because, GNU GPL, GNU LGPL and GNU FDL, allow commercial use.
If you want to link with proprietary software, then use the GNU LGPL.
If copyleft is not desired I suggest you to use the lib/libpng license.
You may just put the license as a comment on those source code files. Or cite properly elsewhere.
From the FSF and GNU view proprietary software is a unethical thing: It's take away people freedom and commonly impose Digital Restrictions Management (DRM).
Creative Commons. GNU. And you can find hundreds of examples at Law school web sites and even use existing EULA content and edit it to suit your needs. ALWAYS have your efforts reviewed by a competent attorney.
