Get a pokemon with theif. then battle him, and use theif to get a nugget off him. Also have amulet coin attached to that you get double the money. after you sell the nuget, you make like 19000
him or lady cindy, the 5th battle and onward, give you 7200 with no amulet coin, or 14400 with. their linoones hold nuggets, which you can sell for 5000, for a total of 19400.
another quick, easy way of making small amounts of money is to have a level 100 with pay day and an amulet coin. 1000 per use of PD.
gabby and ty + amulet coin is OK too, especially after they stop moving. just under 7500 each time.
also, for reference, beating the E4 should take about 10-15 minutes, and gives you 64,200.
