Animal Crossing: New Horizons (Help needed)

Hi everyone. If you play ACNH, I'd love some support if possible. I'm struggling with building up my bells and Nook Miles enough to afford game-furthering options (bridges/slopes, ultimate bag expansion (8000 miles, aaaaa), and being able to use more than 1-2 Nook tickets to visit random islands at a time. I'm currently (finally) at a rating of 2 out of 5, though... so I guess that's a slight accomplishment. I enjoy the grinding and crafting, but Tom Nook is... Tom Nook. I'm frustrated that I can't get to the next big event (KK Slider) a bit faster/easier. That's all I really want to be able to do. >.< But moneeeeey. Ugh. If anyone feels like helping me with this, let me know. I'll give you my friend code. Not keeping my hopes up, lol. Thanks for reading, at least.

Best tips sell turnips. And get many tarantulas to sell.

I would also like to mention grow plenty of fruit trees not native to your island and sell them. Even better if you can sell coconut juice

Turnips are a bit of a gamble. (Literally) I average about 100k a day by fishing and bug catching. Best advice I could give is to dig up clams through out the day, then after a certain time (4pm), head to the pier and do some fishing. Try to net those shadows that are a size category larger than Sea Bass, and don't pass up the medium and small shadows either, as Barreled Knifejaws sell for about 5k each. Red Snappers are also quite nice. But like I said, you're going to want to catch the Tuna, Oar Fish, and Blue Marlins for this season. (They'll be gone starting May.) In the upper rivers, you have a chance of catching Golden Trout in the medium shadows, so keep your eyes out for those. They sell for 15k, but are kinda a pain in the ass to find, given all the other crapy river fish. And after 9pm, Snapping turtles. And for bug catching? Tarantulas really are the best option. Although a lot of reasonably priced butterflies tend to infest your town after you managed to breed or accidentally pollinate crossbred flowers. Like purple or pink colors. They can net you a lot of bells as you loop through the flower garden. Likewise, orchid mantis during the early morning through to about noon also supplement the income rather nicely. Also don't forget your daily glowing spot, and your daily money rock. Those are your most stable incomes each day, for sure. Try burying 10k in the glowing spots, then moving it to a small tree garden where you won't forget it. Or bury 30k if you are feeling ballsy. (There's a chance it will give you 90, or it will default to 30k again, so you don't really loose anything by going 30.)
