Need program to check process CPU usage, if process is 0% cpu usage, email me

I need a small simple program that will be used in a server. The program will run and check "[login to view URL]" processes - on this server there are going to be about 20 of these processes running on different accounts but within the same actual machine. The program will be run from the admin account so it has full privileges. The program will sit and monitor all [login to view URL] processes, when it detects that a [login to view URL] process is at 0% cpu usage it will start a countdown, if the process is still at 0% for 2 mins, the program will email me. My budget for this is something like 20-50$.
