Looking to start a garage based business using a router system (Hopefully ShopBot!). I have been in the signage industry for 10 years as well Packaging and manufacturing for 6 years. I am in the middle of preparing a plan and wanted to get my cash flow chart set up first. Some of the questions that have been boggling me are:

How do you figure cash sales for a small CNC shop year?
$50 to $70 per hour cut charge plus materials and shop labor maybe?

How do you figure material costs for a year? So many materials and many different prices. How do you explain it in one month by month cost.

Is there a good book to reference on how to pull these numbers out of thin air? I want to get my Financing in order so I can present it to banks and lenders.
Thank you for your help,

Bart Thatcher
