Classic startup dilemma - when to ask for the umbrella?

There's an old saying that you should ask to borrow an umbrella when it is not raining because when it is indeed raining nobody will lend you one. Having started north of a dozen companies on 3 continents I can verify that this is true. My latest venture, WrapMail, is looking to raise some money and it is not raining so to speak. In this effort (which we yet have to put focus on as building the business takes just about all available time) I've come across some interesting responses:

Bank: If you deposit $1M with us in an escrow account (that you can't touch) then we would consider lending you $1M. Does this make sense to anyone? Assuming I have the million why do I need the bank for this exercise?

VC: Why don't you build the Sales Team and get to cash-flow positive and then we'll talk. Duh - this is exactly what we would use most of the funding for.

I have many times been on the other side of the table and I view it as one party has an idea and people to execute a part of the way, the investor has money. The risk is always high at these levels where there's zero liquidity in the investment so one tries to balance that risk looking at the validity of the idea, the potential, the team and the potential exit strategies (liquid event). Then, in my case, I jump or I don't.

There's always the old fashioned way of building the business with blood,sweat and ones own money (which I am doing currently), it is less dilutive and a great feeling when success is established. However, it is normally a slower process and being in the viral internet advertising space SPEED is Job 1.

I guess we plug on, the more no's we get means we get that much closer to a yes OR better yet success without sharing.
