I need a sample cron job creation

I have been trying to create a cron job, but I am stoked and need help.

I need to run th following script one per 24 hours:
http:domain.com/wp-cron.php?import_key=Iq_GCn7v0&import_id=36&action=trigger

the following one to run after the above, once or twice.
http:domain.com/wp-cron.php?import_key=Iq_GCn7v0&import_id=36&action=processing

I created both cron under AMC dashboard and added the following hooks in my functions php file:

if( !wp_next_scheduled( 'myjobs_trigger' ) ) {
   wp_schedule_event( time(), 'daily', 'myjobs_trigger' );
}
add_action( 'myjobs_trigger', 'update_myjob_trigger' );
function update_myjob_trigger() {
   // do whatever you want
wp_remote_get('http:domain.com/wp-cron.php?import_key=Iq_GCn7v0&import_id=36&action=trigger');
}//end
//Run the execution script Once every 30 minutes
if( !wp_next_scheduled( 'myjobs_process' ) ) {
   wp_schedule_event( time(), '60*30', 'myjobs_trigger' );
}
add_action( 'myjobs_process', 'update_myjob_process' );
function update_myjob_process	() {
   // do whatever you want
wp_remote_get('http:domain.com/wp-cron.php?import_key=Iq_GCn7v0&import_id=36&action=processing');
}//end

I’m missing a lot here.
First I can’t properly figure out how to write a function that first test the trigger cron has run before running the processing second.
I couldn’t also properly write the timing for the processing cron which timing should be 2 times daily after the trigger cron ran.

Any help will be appreciated.
