I'm interested in serving career changers. What is the most effective means of marketing to this sector? Will I have to spend more marketing to them than I would to an 18-24 year old market?

I've been in schools where the reps have elaborate means of displaying their successes. That is, rep numbers are put on display in the office area or reps "celebrate" their success by ringing a bell or doing something that gets everyone's attention. Do these methods work long term?

Does anyone have any 'tried and true' techniques for getting reps who have been underachieving back on track. Any thoughts about how long to work with underachievers before letting them go?

A school in our area has been using the same radio ad for 4-5 months. Is there a "limit" on the time you can use the same ad over and over without listeners tuning it out?
