Yeah that is a bit of a funny question. No one in their right mind would turn down a job flying turboprops just because they want to end up in jets. You sound really silly.
Grab anything you can, while you still can.
Lets put it this way - how can having 2000 hours of turboprop time be worse for getting a job on jets than having no time in anything?
Do you have a choice? You sound almost as if you have the luxury of picking which job you want.
Good luck anyways!
