One of the major factors will probably be the area in which your business is located. Is the cost of living high?
Will you be renting a workspace or using a space for free? A large chuck of small business resources are used for renting a space. As for fuel, are you planning to make deliveries? Fuel costs can be kept low if it's convenient to use your personal vehicle, rather than renting or buying one...at least for starters.
