Can somebody give me a script advice/example of how to restart services?

I have to restart 17 services, but the first 4 services have to be in the right order and after the restart command is given to one of the services, the next one should be started when the previous one is finished.

I know I can restart a service by net command, and I can build a delay by for example a ping command that repeats for an x amount of times, but I never know in advance how long it is going to take for a service to restart.

Thanks, Kindest regards, Marcel
