First of all, have you done some market research into the area/type of food that will be accepted/ your competitors etc? Not having any experience at all in this industry may not be the easiest start, but thats not to say it couldn't work for you. But...you must have some feedback from potential clients otherwise you are risking an awful lot here!
An example: Recently, ( like 2 months ago) a Frenchman decided our city needed a specialist French Chef doing ready to heat and eat meals to take home, and gourmet foods delivered to offices for lunch. Now, I know what he is paying in rent as I had looked at the kitchen he is leasing for myself, he has on top of that his insurances, gas and power, staff, and every other day to day cost...excluding raw ingredients. I figured he would need to sell 600 of his gourmet sandwiches ( delivered) and 200 of his ready to heat meals each week, to a new market, just to meet the above mentioned costs!! Raw ingredients not included. He is now not in business. Within 2 months all he put into the biz has been lost.
That is absolutely not saying this would happen to you, but make sure you have done your research, have a business plan and a good accountant, and realise that even paying a professional to put some menus together and test them for you, will cost heaps.
Look forward to hearing more from you
