I don't think it's just the amount of time, it's the quality of time. A guy with 3000 TT who's been a CFI most of the time doesn't have the same type of experiences as someone with 2000 that's flown checks, and then flew an RJ or corporate airplane.
I'm amazed at the variety of guys we have a NetJets. All walks of life here. Pure 121, some mixed 121/corporate, some pure military, some on their second career etc.
Aside from your TT, most corporate/fractional companies are looking at what you bring to the table customer service wise. Anyone can fly a plane, they want to make sure you're able, and willing, to do all the other stuff that goes along with the job.
When the economy does turn around, I think it's going to take a while to recall everyone and start hiring new guys off the street.
Best of luck to you.
