Can you Schedule a job inside another job?
Yep, indeed you can! So you are hoping to have one job complete and the last step of that job would be to kick off another job? Here is the command to kick off the next job: sp_start_job

E.g. The first job has a schedule and  final step of the job is to run:

exec msdb.dbo.sp_start_job N'My Second Job'; 


"My Second Job" doesn't have a schedule, relying on the first job to start it.
