You could always use IRC, located in the top right corner on the darkness; or download a client. IRC allows you to talk to other individuals which play this game, and make business deals.
JUST DON'T GET SCAMMED - Use a middle for untrusted traders/higher value trades.
Are credits a problem?
You could always join a faction, which would include a monthly wage. Where you would be working for someone/faction. You could also faction sit, which is basically joining a faction and getting paid roughly 250k but not having to do any work. Working is better in my opinion because it comes with a far larger wage :)
The combine also have a CP (Combine Points) system, located on your right panel where you see your character under your level. All you have to do is donate some Real Life cash or you can click the sites every day of the week and vote for SWC. This does not earn a lot of CP's but eventually you can buy things with them such as the following;
CP Bonus Ships
CP Bonus Vechicle's
CP Bonus Droids
If you don't under stand the CP system, feel free to DM and i'll make you a step by step method on using it. In that matter, with anything really. JUST DM ME!
Hope this helps,
