Salary as director- Tier 1 Entrepreneur ILR + funds

[sm12]

It seems from the form that everyone applying under SET(O) has to provide details about earnings.
Is there a minimum amount that the directors of companies under T1 E have to earn?

I also noticed that one must provide details about receiving regular funds from other people? Is it necessary to provide details about this?

Thank you.

I was also wondering whether there is a certain minimum amount that one should show in one's bank, even though there is no maintenance fund requirement exactly but one has to show evidence of sufficient finance being available?
