Hi paeng,
I have a few questions and if you could answer them it would give myself and others a lot of insight about your situation:
How well do you trust your colleagues? Do they have your best interests in mind?
Is there any way you can cut costs further?
Is there a way you can prove to the banks that you will have consistent cash flow? Do you have promises of purchases from clients and contracts to prove it?
Look at the situation from the bank's perspective. Is there anything you can do to prove to the bank that you will increase your revenue in the very near future?
