If your cron is set to execute the scheduling script every 5 mins, it will not take 30 mins to start sending. Are you sure it takes half an hour before sending?
The next time cron executes the scheduling script, it'll be within 5 mins or less. The scheduling script checks if any campaigns are in 'Preparing' mode and starts sending immediately.
