Chateau Staircase Model Request (Counter-Strike: Source)

Hello.
Today, I venture into the Model/Skin Requests forum to request a model.

In the Counter-Strike: Source map “de_chateau”, there is a specific model of a ruined and destroyed staircase.
The exact name of this model is:

“models/props/de_chateau/ch_staircase.mdl”.

Can someone make a regular version of this staircase? IE, replace the gaps in the staircase with stairs, remove the rubble at the bottom, and fix the collisions so that someone may actually walk on them.

If this is so ambitious of a task, I am willing to pay.

TLDR: Can someone fix the ch_staircase model so it’s not collapsed?
