if you don't have the resources, delivering subpar products using the tools you wrote here (and unfortunately at this day - they're vastly inferior to native) won't help you secure the resources, if anything, it'll only prolong the time it'll take you to deliver your industry-standard product, I'm speaking this from experience after taking on html5 cross-platform projects and porting those, as the customers kept stating that the html5 on mobile isn't decent enough to show as a product, it might be a few years until that changes, and for the meanwhile - don't bet on it.
