My advice would be to make sure your role in the school is clearly defined and articulated to faculty from the start. This can be done by yourself, but having your principal do this or at least back you up may be more effective early on. Most teachers have not worked in an environment with a tech integrator so this is pretty important. The last thing you want is for teachers to think you are the printer repair person or the laptop debugger. From experience, the first year may be as much of a learning year for your faculty as it is for you. I am in a somewhat similar role as yours, but I work at a school with 1200 students (and 3 other tech coaches) and also teach a couple of tech elective classes each semester. I think you'll have an advantage with no teaching load, but this might be offset by the fact that you are on your own in a small rural school. It will definitely be an adventure - good luck!
