I recommend you make a swordsman>knight>high swordsman>lord knight> rune knight OR a archer>hunter>high archer>sniper>ranger. Both of these classes have very good farming abilities and also solo capabilities. If you can find a friend or guild making a priest is a good class because people are ALWAYS in need of them. If you get a bit of funding, wizards are always in need of during leveling parties. If you can build some fg and try to exchange the fg for zeny in game, then i recommend it. Dont build a creator because they are hard to level unless you are VERY funded.
