2M in 20 day was doable. There's a very very broken hunting ground in Marusta Reversed, between the time extension block and the 2 wide road and the 4 fight block, at this spot you either cycle in place (4, 6) or hit extension block (3, 5) or hit wind (1) or worst of all get a 2nd fight a bit off location (2). Then cycle around and rinse and repeat, you can usually end up fighting for ~an hour until the timer expiring (record was close to 2 hrs because, with a bit of luck, your timer actually ends up increasing past the initial 40 moves). I usually get 1k-2k xp per segment with the 2 Skill build (and Wiz's 2 SP recovery on wins for sustained recoveries)
Most importantly, with Wiz's spoil fishing, you will end up getting a crapton of Jelly Cores (from Blue Jellies) which sells for 1.5k ea, and Fire/Wind Spirit Stones from the Spirits which sells for 2.5k ea, which more than makes up for the difference.
p.s. Just remember to bring a antidote brooch (10k at wiz store), which you can equip and unequip at campfire to heal the occasional poison from slime and hornet.
As for daily, don't forget to pray for chest rewards every day. You should get 20k in treasure a day in Dearshiel (and most importantly, good EQP to improve your farming ability), not counting the ones you get from the Frostlin Lair.
Any UR eqp is usually good, I was able to get Earthshaker the mace relatively early 2d6+18, and then a repeating bow that hits twice.
Big gold blobs are (aside from ~500k you tend to end up from misc quest, job rewards, and map pickups and after buying granny's med for 80k):
1m for clearing Dearshiel floor 10
~300k in all the treasure you get from Dearshiel and other places, and more with Wiz's Citizen's Ability (Dont sell until the negotiator perk to maximize)
300k from clearing Lord's exorcism commissions
Then the rest can easily be made up with what you sell at the fence, like those jelly and stuff.
I was able to clear 2m without claiming the Lord's 300k, and had a lot of stones left over after selling a bunch of jelly cores and circuits (from floor 10).
Day by day saves attached through day 20, not complete game save, just my day to day progress through day 20. Stick to Wize and Rishel because they are skill based, so they almost always move first, allow for more sustained farming due to less damage.
EDIT: I'd say the hardest part of the playthrough is being stuck with Grant until Day 7's Wize quest, as that required me to restart the dungeon every time he lewded the FMC on the green checkmark or pink heart tiles in Dearshiel. That and getting through 10 people at the tavern without a molester...
