Pull surface points various strength to create a grid

Hello, I’m new to grasshopper and I’m trying to crate a grid on a surface, kind of a corrugated finish. I would like to be able to control the number of sections and the way the points are pulled. The image will clarify. I was able to achieve the effect selecting alternate control points of the surface in the vertical direction, move them in N direction and apply a weight of 5 to the points to achive that acute effect.
I would appreciate if anyone can help me, I’m open to pay for the time

That’s exactly what I was trying to accomplish, Thank you so so much!!! This is really helpful.

Do you think there is a way to pull the points in the central area?!
