Here's a tip: working composers typically assemble their templates from dozens of libraries, not just one. That takes not only an investment of money, but a significant investment in time.
Half the science of being a working composer is researching the best of the best for each instrument, finding which ones are efficient to use and how to properly manipulate them to achieve the best degree of realism. Even just that can be a full-time job - never mind the hardware, software, workflow, audio engineering concepts, and of course composing and orchestration skills.
