I see two ways of starting the work of the company:
1. Focus on colony-alien interactions and
2. Allow for both types of interactions - between colony and aliens plus colony broadcasting to earth.
The second arrangement seems to me more energetically vibrant. The fact, that the humans can channel their excitement back to Earth will help them to manage the stress of meeting the aliens and learning many new truths. To keep broadcasting safe, the broadcasts of the colony to Earth can be very limited in scope and censored.
So, initially, I think it would be very helpful to have seeds of future activities present in the colony from very beginning:
1. Cultural work - creating new alien-aware human culture.
2. Educational broadcasting to Earth- to broadcast educational video materials to humans, initially, without revealing alien presence and off-world location of the broadcast. Initial materials will be best delivered as YouTube videos, blog posts and text and video messages to news agencies.
3. Education of MIC people. These could be educational materials exposing the truth about MIC activities and aliens to MIC people. Since MIC people often know little about what different parts of MIC are doing and often are under-educated, their education will help much redirecting MIC from a suicidal to constructive path.
4. The school for children of colonists: Clinic - by humans and aliens for humans. The clinic will allow humans and aliens to improve the art of curing humans. Later, this clinic can be used for treatment of humans visiting from earth and for expanding to earth locations.
5. Touring agency: Since human politicians and MIC people are suspicious, the best way of educating them about aliens is touring alien planets and talking to aliens. Interactions with both types of aliens would be helpful; the ones related to Earth and ones having no relation to Earth.
