Hi willem, you should probably consider going to some Rhino/Grasshopper training courses.

You might find something here:

And if you search around you can probably find video courses like this:

You might actually start out with Rhino training courses for a while first and then Grasshopper courses after that.

It could very well be a 2-3 year long learning process to get to where you want.
