You have many options.
1) Write the thing and propose it to an artist to draw for you.
2) Get some money, and pay an artist to draw your stuff. Like commissioning
3) Learn to draw, so that over time you can make your dream a reality without dropping a single cent.
4) Throw away your insecurity about your inability to draw and start drawing it and hope whatever you throw against the wall, sticks.
This seems mean spirited but...
There is no but.
