If u you have patience and time... u you can hunt wasps and bears... every honeycomb and bear paw can be really well sold.
U can also try your lucky in some hunts, like witches and mummies that can drop very rare itens items (stuffed toad and mini mummy) and u you can easily make your 1kk with one or two of them.
Furthermore, u you can try the Hunting Horn daily task... or make 500 chars to get 500 Diapasons and keep selling them until u you get your money.
Well, at any choice, time and luck will be needed.
So, no, it's not easy, although it's possible. :D
