There are folks around who specialize in pattern making. I designed some pants years ago and it was $1k for the pattern, but I received and owned outright, a digital file for all sizes xxs-xxxlarge I believe. This enables you to obviously send the file digitally to a manufacturer, a pattern plotter, etc. Ownership is a must.
Invest in yourself and your ideas and hunt a pattern maker down, run them through your vision, and be fearless. Good luck!
