Hunter,
The bank is willing to issue 3 cards for you, James and Sarah, of limit about $25-30k a month.
However the bank is not willing to take Hudson's cash balance as guarantor, because it is a new company, therefore the bank is asking to take $30-50k as "payment collateral" to the card issuer.
Let me know if this works for you, I will instruct the bank to proceed.
Thanks,
Mervyn
