Unfortunately in the current climate jobs are few and far between, there are a few companies that will allow you to have a SSTR. However generally anyone recruiting requires a TR+hours on type, the minimum generally being around 500. However again it is all down to being in the right place at the right time, I know people who have less than that on type and have recently found employment, and I know people with thousands more that are unemployed. Paying for a type rating only can be hit and miss, again I know some people who have paid for their own ratings and have recently gotten employment, I also know people who paid for their ratings and can't get a reply to their CV's.
I would definately start by saying, get the idea that cargo companies are easier to get into, out of your head. There is no difference.
Good luck
