What part of the country?

In my limited experience, I'd just say to watch out for operators that promise you everything under the sun... (charter 9 bazillion hours per year, one trillion dollars a day in revenue etc...) and also to double check that what the owners say they will do as far as maintenance and staffing, actually happens. I flew for a dirtbag 135 that would make the "9 bazillion hour per year charter and the 1 trillion dollars a day in revenue" promises, and they'd also quote 3 pilots for the aircraft, 2 captains at 150k/yr and 1 fo at 120k/yr, (not including training) and all in-house maintenance with the same costs as the company owned aircraft realize. What happened was that they'd pay the pilots dirt, fire one pilot so there's only 2 left, and they'd charge exorbitant rates for maintenance, and they'd never deliver on the promised hours or revenue. The uninformed owners never seemed to check on the company to see how they're delivering on their promises.
Inevitably, at the end of the 2 year contract that the owners signed, they'd find greener management pastures elsewhere, but for the 135 company, it didn't matter because they raped the owner for 2 years and "got theirs".
Bitter rant.....over.
