We started an IT college in South Africa offering IT qualifications only and have been struggling to attract students. When we do get students, mostly don't qualify to enroll for the programmes according to the National Qualification Framework. I come from a software development background and have no marketing experience which has made it difficult to market the institution. We have a very limited budget and need simple but effective ideas to implement for our marketing strategy. We have used social media but it has not translated into the leads we need.
Looks like you have already defined your ideal customer;
You need to find out where the potential students spend their time - Online & Physically - and meet them there.
I'll start with the option, which I think has the most potential:
and the answer is NOT online - do not underestimate the value of networking; going to meetup's - interest clubs - sticking adverts on buildings, bus stops etc. with little rip-off pieces.
- do they spend time on facebook? probably the most undervalued forms of marketing
- you can do a very narrow targeting through Google Ads, but you did mention a very low budget.
Hope this helps
