Not to be negative, but have you checked into both the source of the offer and the people you'd be working with? Like independent verification/recommendations? Flying a new model in to a city that's already pretty close to saturation with pretty girls looking for work is a little unusual and describing the location in terms of an area code sounds warning bells in my head. LA is the center of a lot of cool stuff, but it's also home to some pretty shady people too. Be safe.
