Financial Model for e commerce start-up

We are starting a e-commerce business for the Nordic / Scandinavian markets. As such, we need assistance to develop a financial and budget model. We need assistance from someone well adversed in this that can help construct a model taking into account various scenarios / sensitivities.

I need someone who can advise in this critical, early phase so relevant experience is a MUST

Please let me know a bit more about what you have done in the past and we can continue discussions.
