If you have the know-how, I'd recommend doing some procurement contracts from the pirates.
If everyone hates you, then I presume pirates are no longer hostile towards you/very close to the -50 mark? Pirates ignoring you is a welcome bonus
It is much easier to keep your fleet small. Having 3-4 Cerberi is great. The only thing you really want to expang is your account balance. Not only will you be able to do some more risky (profit-wise) runs, but you can buy a few combat ships and stow them away when you eventually decide to raid a few small merchant convoys.
When you do so, I recommend the Magec and Hybrasil systems. Since there is not much point in doing otherwise I'll assume you have Technology specced decently - Navigation skill will give you an edge while lurking through the nebulae/asteroid belts.
Also, the Guayota's disk (huge dust ring around the star) is an excellent spot to practice evading patrols, ambushing, and getting the feel for sensor ranges in general.
One cool little thing is that if you navigate to an asteroid your fleet will "stick" onto it, allowing you to drift around while not moving at all - your sensor profile will be close to naught.
My glory smuggling days were during the previous game version, zooming around with a fleet of combat freighters at burn speed 12-13ish and making hundreds of thousands off trade disruptions and food shortages. Since economy and pricing has gotten quite complicated, I primarily do small-medium procurement contracts.
