This question is by no mean specific to Julia. You have to release the software under GPL (v2/v3) and of course as a copyright holder you are allowed to use it commercially. If you want others to contribute to your package you need them to agree that the code will be used by you under a commercial license (have a look how ubuntu handles it)
One of the prominent software that is both GPL an commercial is FFTW (e.g. part of matlab). Cheers, Tobi Am Freitag, 5.
