[dead man walker]

Hello,
I'm an eventscripts scripter and an owner of multiple servers. I have found that eventscipts, in several places, is not as powerfull as sourcemod, for exaple when it comes to my request, the admincall plugin. I have seen scripts in here that send a message to jabbe and other messager-programms, but the closest to me seems to be a Steam-chat-message.
Could someone scrip this plugin for me and probalby many other users out there a script, that does the following for css.
A player types !admincall <player> <reason> into the Css-chat. That message (the reason) gets send to all steamIDs listed in a file on the server (the admins). After having sent an admincall the player has to wait x minutes (configurable in a file) before being able to type !amincall again.

I would very much appreciate if someone would spend a little of his/her time.
Thank you in advance.
