I think it is impossible to know whether a service has finished or not unless the service itself lets you know that.
If you just check whether the service is still alive - it may be waiting for a server response - or it may have finished and processing some other application's requests. So, I guess you have to request that all services let you know by a callback when they are done, so that you can continue with the next service. Probably you also need a timeout, in case a service never finishes.
