Create a few expense/budget

We have started a new project and I would like the expenses and operating budget to be defined: 1) a weekly worksheet on one side the costs and the other side the employee would enter expenses. At the bottom of the page the total for the week would need to be entered 2) Start up budget draft 3) Budget for operation for 3 agreements and for 6 agreements 4) Overall company budget along with the break even point. we would like the documents to be color coded,clear and be easy to edit as we go along. You must understand formulas for excel and like to draft a nice, user friendly documents.
