You need a source of capital to carry you through the receivables period. Basically you've got three options:
-Borrow money to finance the receivables
-Find investors to contribute equity to finance receivables
-Sell the receivables (factoring)
or some combination of these.

In my experience you're talking about making the same leap that a bathroom renovator might make to become a home-building contractor.
The difference in that business is also capital.

Arrange a call if you'd like to discuss your particular case. I can run through a few questions with you and help point you in the right direction.

Best,
