Sign Language

I'm not sure what group to post this in but I'm looking for some insight from anyone that has anything to share. I currently teach 1st grade and am looking at getting my Master's Degree. I want to do something with sign language and the deaf/hard of hearing community, like interpreting or something along those lines. I'm just not sure how to go about it all! My questions are:

1. What type of grad program should I look into? (Preferably majority online)

2. What type of job opportunities are out there?

If you have any advice it would be greatly appreciated!!
