In ArtMoney, you search for the exact amount of sun that you have. (i.e. You have 50 sun, search for 50, spend one, search for 25.) Sun is really easy to find because of that.
For money, you search for the amount of money you have divided by 10. So if you have 400 dollars, search for 40. When a coin bumps you up to 410 dollars, search for 41. You'll have the money address in no time.
Hope that helps!
Second of all, try making a topic on this board:Link
Just enjoy the game as the developers intended and then see if you still want a trainer..
