Yeah, that's an OpSpec you can get, but in general, I'd say charter customers probably feel more comfortable with two pilots.
There are companies that will hire you with less than 135 PIC mins, but you have to meet people. I should know, since I'm employed by such a company. But I never would have gotten the job if I hadn't talked to the CP for 30 minutes at a job fair. Most of my fellow instructors talked to the airlines, but my buddy and I talked to the 135 outfit. We both got called, the others have run into the downturn at the airlines. A matter of timing and choices is status quo in this industry.
