Sweep a handrail profile along an irregular helical curve in 3D?

Hello all I am in the custom iron railing business and would like to provide my client with a 3d rendering of what the railing return will look like at a landing. The shape will be a helix similar to a volute and retain the handrail section profile's vertical orientating (no banking or twisting or tilting along the path. I have been successful in the past, but only with a simple rectangle, by creating a mesh between two legitimate helixes and press pulling or extruding that. This is something I will need to know going forward, having a method of accurately creating these 3d renders in such a way I could use them for shop and installation drawings as well.

 

 

 

 

 

I am trying to replicate a shape like this...

This is what I keep having happen when I do get a successful sweep. This was broken up into three parts.

Anything you have or commands to try would be very much appreciated. This is my first post on the CAD forum, but I am stumped. Thank you
