onenewbrazil it varies, my internet start up should have been looking for funding from day one. In reality though banks want to see income, and where your money has been and is being spent. Here is what I am going to say the bank wants to see,
Income how much and for how long. Is that income rising or falling. A business plan, the better this is put together the better your chances are. I am sorry I can't answer questions about private funding sources have never had the need for them.
Good luck to you
