Hello bud, long time no business
45-99 Fish with Swords/Tuna sold raw guarantees you 26.9M to 76.3M.
You'll need 108K on average, raw lobsters to get to 99 cook from 40. How many you will/wont burn to resell back to buy more is beyond me, it is too influenced on your cooking lvl and if you have gaunts.
Now, that being said, 68? is the level you stop burning lobs with gaunts and 73? is without if I remember correctly. If that is indeed correct, that means you'll only go thru 8000 of the 108K lobbies, and the last 100K you'll not fail to burn. If I did my math right.
Which would be 45M~ average to buy the lobs for the entire job, selling all cooked ones back (Not including the 8K from 40-73 because im not sure how many you'd successfully cook). You'd waste 9.78M.
So like 45M to buy, 35.9M to sell back 100K cooked lobs, and 9.78M lost profit.
It's a cheap 99 that's for sure
And time? Depends which offer you go with. Speed-training is definetly the fastest, my educated guess is a week or two?
Let's see your average skill shop do all that work for ya
