look guys, I have some friends in the UK, programmers, moldovans settled there, they can as well give me a handful of help... but, frankly I see very few reasons to go commercial in such a way, but the one of fast enreachment (which i think has never worked). the core idea of Kolibri is that it is neat and tight, lightweight and it's nearly ready, you can easily 'sell' it to so many interested parties. when i wrote the word sell in quotation marks i meant that you actually need to sell your programming time (man-hours) and still be independent. if your kernel will prove functional trust me you will have many business offers to adapt it.
as for now, Kolibri has lots of strong points which can be utilised as vehicles for promotion among a large group of users/consumers. also you have to bare in mind that once you appear on the market there will appear other competitors who will design similar OSs much tighter and much more robust, because having your 'proof of concept' working a lot of other will adventure to repeat your path. so imho, the only thing that is saving you now from being plagiarised and left overboard is that your OS is opened source project, mainly maintained by enthusiasts.
trust me, when people start working for salary it's no more art, if you can follow my word twist
