Depends on your needs mate , you can go on with
Vanguard -trooper / Powertech , you can alternatively go with Shadow / Inquisitor
I would personally choose trooper because he gets a strong healing companion
like from the first levels , the aoe he does is insane and he will just keep pulling more.
Professions for this need to be Archeology , Slicing and scavenging ( for $$ pure income ).
Using 5/5 companions to send out for credit boxes all the time is a bread winner also.
Hope this helped +rep if it did
EDIT : Make sure you pick a crafting class to compliment your farming class should you choose pure $$$ professions on your main char.
