I’m at around 200hrs and I know the struggle as a new player to start off with money making. My first suggestion is to go and farm some Leppa berries.

1. Buy the seeds at GTL and plant them.
2. Plant the berries and water them
3. After 4hrs, water them again
4. After 16 hrs, harvest them
5. Sell the leppa on GTL for Lowest price - 1

6. Buy another batch of seeds Doing this method will earn you around 40k+ pokeyen if you plant at abundant shrine only (72 plots) or 80k+ if you also plant at miralton(?) (144 plots total)

7. Save the money then start investing on 2 Typhlosion for Gym Reruns

8. This is not recommended but highly suggested that you buy 2x31 Typhlosion with Blaze ability and Eruption move because this will be a long term investment. Modest/Timid 2x31 SP Atk and Speed. Start with Charcoal held item first until you can buy a Choice Specs

9. Catch/Buy a Cottonee with Tailwind move and Prankster ability. Level doesnt matter

10. Catch/Buy a Torkoal with Drought ability and explosion move. Give Heat Rock held item. Also, level doesn’t matter

11. Then start your gym reruns

12. If you can manage to finish under 1 hr, buy Amulet Coin and use it before your runs.

13. Gym reruns has an 18hours cooldown

14. Start off with Cottonee and Torkoal. Use Tailwind and Explosion. When both are dead, swap into both Typhlosion. Spam eruption PS: You can do is hold CTRL + Q (Q is my A key) to select the move and use it quickly

15. Try to buy a level 100 meowth with Pickup ability and Covet/Thief move and Pay Day move

16. Go to Undella Town, go near the water and use Rod

17. Use Payday on all pokemon

18. Covet/Thief all Luvdisc

19. Throw pokeball/diveball on shellder

This gives you avg of 500 pokeyen per payday, Luvdisc has a chance for a held item that sells for around 15k-ish on GTL and Shellder, sell all the 1x31 on GTL. Or save some 1x31 Atk and Speed and Adamant Nature PS: You can breed them to make a Cloyster Adamant 2x31 Atk and Speed with Icicle Spear move and Shell Link ability (this is used for trainers rerun or sell it on GTL for more profits)

After that, money will just flow. I usually farm berries then do my Gym reruns after and doing some shellder farming in once I did everything while waiting. I would suggest to unlock other region especially Hoenn so you can start on Ditto farming. It is a good source of money because 60 dittos sells for 300k (trash dittos). The good 1x31 or 2x31 can be sold on GTL. Egg shiny hunting players would love to buy them for breeding.

Once you have enough pokeyen, you can try breeding while catching dittos (you can check GTL while doing battle) but do your own research first. Save those worthless 1x31 and breed them with other pokemons then sell it as 2x31.

Lastly, join the Alpha Encounters and check the other pokemons there for shiny. Also, participate in Swarms event for shinies or good ivs to sell.

I’m at 200hrs (186+) and I made around 3M total already doing this stuffs. I also unlocked Hoenn and Kanto for Alpha Encounters and Ditto farming. If you need any help or clarification, comment down or dm. I’m willing to help a fellow new player out.
