Financial Model for Consumer Facing Startup

I need a business plan and a financial model made. One that I can explain every single detail of but that will also be compelling to the type of investor who cares about such things. (Some do and some really don't, but I want all my bases covered.) I have a revenue model in a very broad sense, but I need it translated into math. I have a pitch deck that's very pretty and easily understood already, this is just really for the investor that feels better with numbers in front of them.
