Developer of training programs

I am looking for a foreign language training program developer. I mean, I'm interested in someone who's had a similar experience in this field. I represent a foreign language school and we would like to develop a program that would allow you to learn various foreign languages at the elementary level and then decide which language they like best and either download full-fledged video / program lessons (lessons programs - we also hope you will participate in the development) on a fee basis or go to our school.
