insurance business cards

Starting my own small business?
I have a project for my Interior Design Business Practices class, and I need to know some average costs of differnt part of "my own business." I am having trouble finding online.I a building 3000 square feet and need to know the averages monthly: Utilities such as electricity, water, garbage collection, telephone and fax. Promotional materials such as letterhead, business cards, e-brochures, advertising. Supplies such as pens, paper, drawing supplies and postage. Salaries as Minas, Partners, Sales Manager and a receptionist, safe for me and staff. Finally, other expenses such as property taxes and insurance.
Search the classifieds of your local newspaper for rent. Visit a store paper supplies. Call the utilities in your area for other expenses. (You do not think that would make his task for you, right?)
