Do some data entry -- 2

I have some work, in an Excel spreadsheet. I am looking to build a excel sheet to keep track of some investments and yield that each create. Each property will yield X interest over a fixed term in months. And below that each client/ investor will receive X % interest per month. This will be distributed monthly to them. And I have a partner and we will share the profits 65/35. Could you help me build this spreadsheet in the next few days?
