Do you think businesses would benefit from an online course that teaches Spanish for business & insight on the Latin American customer in US?

Hi All: We need some feedback on an online course we want to create. Did you study Spanish for "10 years" through High School and University to then freak out when a spanish-speaking person approaches you and says "Como estas?" Basically, we want to create this online course for business owners, entrepreneurs, freelancers, sales agents, and marketers to learn USABLE Spanish that could give them the competitive edge in the workplace. On top of learning keywords & phrases in Spanish, the course will teach you about the Latin American consumer, their spending habits, their interests and provide insight on their motivations, culture and values. We think this could be greatly beneficial to businesses that haven't quite tapped into the Latin American market with their product or service. Or for example, a Realtor or Sales Agent who wants to gain an edge over their bilingual co-worker. We aren't guaranteeing fluency with the course, but we are guaranteeing the skills and insight to completely charm a prospective Latin American client to buy into your product or service. All of the online course information you can find here: www.colombianplusgringa.com Any feedback is appreciated! Would you benefit from an online course like this? If so, what field of work are you in? If you won't benefit, do you know someone who would? What work do they do? THANK YOU!
