Changing schedules for a Job outside SQL Server

Subject: Changing schedules for a Job outside SQL Server

Below is the script of a Job called "eFIMS_SendEmail" that I wish to
run.  The intention is that every day of the week the job will execute
a SPROC at timed intervals.  For example, the SundayRun schedule will
run once every 1 hours from 00:30:00 to 23:59:59

However, the clients have stated that they want an interface to this to
enable them easily to change the start time and frequency interval for
each day.  It's an easy matter for me to paint them a form from within
the target application to enable the user to enter the start time and
interval for each day.  I can then pass these as parameters to a SPROC.
How can I use these values to change the schedules for the job?  For
example, if wanted to change SundayRun from once every 1 hours to once
every 30 mins?  I know I could do it the hard way, by using string
manipulation (e.g. find string 'SundayRun', then look for the next
occurrence of @active_start_time, @freq_subday_type,
@freq_subday_interval etc. and do some replacement) but this seems
somewhat tricky.

Many thanks
