Out there refers to something away from you. Out here refers to something near you that is away from someone else. For example: I am from Oregon, USA. Out here we speak English. Out there in Mexico, they speak Spanish. I teach English classes. Let me know if you are interested in booking a class.

The "out" part tells us that it's a location away from something else. For example it's not near a city, or it's in the ocean and not near land. "Out here" is a place near the speaker. "Out there" is someplace not near the speaker.
