Do some Excel Work

I would like a excel template for project management suitable for the building industry. I would like an interactive excel spreadsheet that will allow me to type up a purchase order on one page and transfer key data to another page creating a index or summary which is called a call forward sheet. I would also like a diary built into another page and a Gantt chart again changed thru the dates of the purchase order or edited from the Gantt chart itself with extras like extensions of times and what not. I have the data for the template. I need someone I can communicate with via wats app, email and viber. I have 10 jobs which once the template is created and functioning I would prefer the creator to input. I will set up dual access to google docs account allow seem less relay.
