Catering equipment

In an effort to maximise revenue, my wife has recently begun a business making cakes for local individuals and businesses. Like any business activity, there can be a fine balance between making a profit and making a loss.
As well as the ingredients for the cakes, a calculation of energy used in cooking and distributing the cakes has to be taken into consideration. Other cost considerations are the catering equipment which has to be of a high standard, and associated costs such as website and business card production. Naturally, website costs are low as I have created a website for the business and we also set up an associated Facebook page.
This type of business allows a stay-at-home mother to work in her own environment and still be available to do the 'school-run' and even look after a child when school is out for whatever reason.
