There are several places you can mine Premium Scrap which, while less profitable than some other ores, can still make you good creds. Sigma 13 has fields that are relatively close to good sell points.
Your ID is quasi-legal meaning you're able to transport goods for either side of the law or both. Keep in mind of course that you're not exempt from either side of that same law. You can be fined by lawfuls or pirated by outlaws just like everyone else.
The default suggestion is smuggling... but it's not particularly profitable as the mod stands. It's really more of a roleplay choice to move illicit cargo than doing so for profit. Don't get me wrong, you can make creds smuggling or blockade running but it's typically less profitable than legal trading or dealing with ores.
There's a market for interesting information. This is not an opportunity to metagame - or share info you read in a forum thread or witnessed in a Skype channel. If you get screen shots of interesting system chats while flying around or incriminating pics of ships carrying interesting cargo there's a market for it; if you can find a buyer.
If you want to be a junker pirate Kusari is your stomping grounds, but as with smuggling, it's more of a roleplay preference than moneymaker.
