Hey Fluffs! I'm not entirely sure I fully understand your visitor message, but I can tell you that I really want those sets! If I have to pay you in advance, that is no problem at all
The only thing I didn't understand was about the 400,000 bells figure. Did you mean 400,000 bells per set, for a total of 1.6 Million Bells, or 400,000 bells per order, for 2 orders, at a total of 800,000 bells? Because if it is 800,000 bells for all 4 sets, I can totally do that. I am happy to come to your town and pay the whole amount straight away.
Or to make it a nice round figure, 1 Million Bells for the all 4 sets
