Thank you all for your great supportive responses. I've said this before but you guys all ROCK!!!!!
I have heard back from the owner who tells me that I would get $10-12 an hour to start and after a couple of years, could get to $15 an hour.
He then said that there was another position available as an office administrator but it would only pay $12-14 an hour but would require a commitment of 3-5 years.
I know that the pay is lower than what I get, that's not what made me say no. He said that a lady just started on Friday and that if my French was good that I could replace her. To me, that is not ethical and if I left my stable, permanent job just to be let go a week later for a more qualified person, I would be devastated.
I'm glad he told me that because now I am sure that it's not the place for me. I'll keep looking.
