If you have the 135 mins, then Aero Charter would be good. I see that you have under 300 hours on your profile though, so you would be a long ways from the 135 mins unless that's an old number.
There is also New Mexico Airlines, they fly Caravans and use FOs but I don't know what they want for minimums. They don't pay the Fos very much so you might need another job while doing that.
I would probably stay away from South Aero...definately never heard anything good about them from other pilots, plus I've heard you have to pay for stuff that gets broken if they deem that it's YOUR fault.
