Looks like you have already defined your ideal customer; Next 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. Online: - do they spend time on facebook? probably the most undervalued forms of marketing - quora - you can do a very narrow targeting through Google Ads, but you did mention a very low budget. Hope this helps Sylvia
