50,000?
Holy ****. Well, I calculated I will have 7k lobsters (approx.) total when I get 80 cooking (once I reach that, I'll move onto sharks).
I have about 4k cooked lobsters currently (I have about 2k uncooked lobsters to cook, and I'll need to fish 1k more).
Since Prayer gets priority (sorry, she asked first), only 6k will be left after she buys her 1k lobsters.
If you want to buy all of them after that, it will be...
85 x 6000 x 0.9 = 459,000 GP
**459,000 GP is approx.
Sorry, I can't supply 50k lobsters, BUT: I have about 3k uncooked sharks which I will cook and sell in the future.
