I can do it for one dollar per hour. We'll teach her how to do some scripting and browser extensions. And at the end she will be a basic coder. However, I will only teach if your girlfriend actually wants to learn to program.
Do you have a budget? I'm sure that would help narrow down the search for you.
I can help with that. 30 usd an hour.
The best CS-for-beginners course is Harvard's CS50. (And you can take it for free online through EdX.) It's fun, but you learn a lot, and you get actual coding experience with coding tools.
There's a lot of free online support that comes with it - Reddit, plus virtual "section" videos, etc.
