Execute sp_start_job from stored procedure

I need to disable and move orphaned computer objects in my Active Directory. The SQL Agent has permission to do this. I have created a stored procedure for the task with intentions of executing it with sp_start_job. However, I cannot execute it in SQL 2005. How can I grant permission to this (login) to execute sp_start_job? This is all run from a web page and NOT the Query Window.

The Agent is just a robot itmusthave correct permissions to run Jobs and other things replication included. So you clone admin level permissions to run it. Try the link below for SQL Server proxy account. Hope this helps.
