NoOb needs help making a plugin

[MoOfTaStIc]

Complete noob here in need of either a plugin or help building a plugin for metamod that will allow users to freeze and unfreeze props using the ent_fire commands, A: without sv_cheats being on and B: commands such as freeze and unfreeze that allow the user to type bind (key) freeze, and bind (key) unfreeze. I know that for the sv_cheats portion you have to use AcceptEntityInput(ent, "DisableMotion", -1, -1, 0), and probably AcceptEntityInput(ent, "EnableMotion", -1, -1, 0). That is about the extent of what i know about this, However i am very willing to learn. I tend to learn better by first hand experience and not by reading, this is why i have come here. Any help would be greatly appreciated.

What i have so far is...

#include <sourcemod>

public Plugin:myinfo =
{
name = "freeze unfreeze plugin",
author = "MoOfTaStIc",
description = "My first plugin ever",
version = "1.0.0.0",
url = "http://www.sourcemod.net/"
};

public OnPluginStart()
{
native bool:AcceptEntityInput(ent, "DisableMotion", -1, -1, 0)
native bool:AcceptEntityInput(ent, "EnableMotion", -1, -1, 0)
}
