I hope that you do carry thru with your plans to learn ASL.
How have the employees been communicating prior to your arrival? Do they have any suggestions? Can they show you some basic signs that are used frequently in their daily work?
There isn't any practical technology like that available yet.
How much interaction do you have with them?
If you're having meetings or instructional periods, you should use an interpreter. (Yes, even non-profit organizations use interpreters.)
