Help in choosing a license

[James McGovern]

Been busy making the case at work to take some inhouse code we have written
and open source it but would like to place the following constraints on it.

1. You may use the software in any system that you do not sell for no cost.

2. If it is incorporated into software that is sold, then you must implement
100% of the ideas contained within it if written in another language or if
the same language, you cannot remove functionality.

3. It is free to use in any context for the industry vertical it targets but
if modified to support other verticals then a royalty should be paid.
