Stock Sheet Control

I am looking for a freelancer to develop a stock sheet control sheet for my business. I have 3 restaurantes, and I need to keep track of both raw materials and finished products for each one of them, inside the same excel project. Currently, I do not have any system in place for stock control. The ideal candidate should be experienced in creating inventory tracking systems and have a understanding of data management. The level of detail required for the system is basic inventory tracking, minimum inventory, product inputs and outputs, and transaction between my 3 establishment. The sheet should be easy to use and provide real-time updates on stock levels.
