Is there a licence out there that reserves my right to use the software commercially, however permits redistribution and modification of said software for non-commercial uses?
Basically I want to be the sole person who can distribute it for commercial purposes. However, non-commercial distribution and modification is open for everyone.
When you are the copyright owner, you can define the terms of use much to your liking...
You could require your customers / licensees to use your software under a license such as GNU GPL, Creative Commons NonCommercial ShareAlike or anything you deem appropriate.
Yes, you simply need to use multi-licensing to distribute your software under two or more different sets of terms and conditions. There are a number of products using this approach, one of the good examples is MySQL.
It's a typical case when license templates will not help you much.
Because you don't want to write your own license youself, or worse, copy/paste paragraphs you don't understand from the templates, you really need to hire a lawyer if you are serious in doing business in software.
