You would not go to a garage and ask the mechanic o fix your car for free. I am not sure why you should ask a patent attorney to do work for free. 
 
I highly recommend hiring and paying a patent attorney. 
If it were simple, you could do it yourself, and this can happen. 
But most responses require skill, education and experience to respond to.  
This is obtainable for a reasonable professional fee.

In your response to the patent office action, you would need to distinguish the terms "aperture" and "trench" clearly. An "aperture" generally refers to an opening or hole, typically one that allows the passage of light or matter, and it can be of any shape. It is often used to describe a feature that goes through a substrate or medium, allowing access from one side to the other. On the other hand, a "trench" is typically elongated and has depth, creating a recess within the surface of a material. It does not necessarily go all the way through the material and is usually created to define a boundary or to house other components. The two terms describe different structural features, and the clarification should focus on these differences in the context of your invention. If representation is required, you should seek a registered patent attorney or agent to assist with the official response.
