I don't know your experience, or where you want to go, but $750 seems to be underpaid. Maybe people are doing the job for that, but the work/responsibility of chief pilot would seem cheap at twice that price. Others will be better informed than me.
With the current market I'd think that either twice as much money would be reasonable - although maybe not available. Having said that, maybe chief pilot experience is particularly valuable for you and therefore worth factoring in place of lost salary.
It would be interesting to know what others have to say on the subject. To summarise, I think it's too little money.
