Job: Combining the Civs Addon with the Purge Addon

I have three addons:

https://www.gmodstore.com/market/view/the-purge

https://www.gmodstore.com/market/view/civs-wandering-npcs

https://www.gmodstore.com/market/view/civs-cops-npc-police

Essentially, what I want to do is have it to where the NPC's (specifically the cop NPC's) de-spawn during the Purge time on the server. It is a rather simple function, I just do not know how to write it. You may do it any way that you like, all I need it to be able to upload it to the addon folder in the server, so a plug and play type addition. I am thinking you could probably just add a function to the civs addon to call on the purge timer and force de-spawn function, and then re-spawn function when the purge ends. That is all I need for it to do. Please let me know if you are interested, and the price is pretty solid. Feel free to contact me. Thank you.
