Umm you are going to sell chocolates from out of your "mums" house and quit a proper job to do this?

Do you have a business license to run this "chocolate business"?

How exactly are you going to get customers selling (homemade I believe?) chocolates? Are you going to knock on peoples doors? You are not going to find many people at all who want to buy from your small "business". There are many factories that professional manufacture chocolate- I know my friends work in one- what are you going to compete out of your kitchen?

I am sorry if I sound skeptical, but it seems to me your idea is highly unrealistic- spreadsheet or not. Do you have machinery/equipment to make large amounts of chocolates?

You are not going to make enough chocolates from your mums normal kitchen and sell enough to possibly come anywhere near compensating for the loss of income from a proper job.

Many major brand names provide chocolates, how are you going to compete? No offense but I personally would not buy some "homemade" chocolates off someone that knocked on my door, and no local business such as deli/supermarket is going to be interested in homemade chocolates.

I am not trying to be nasty, but I can't personally see how your plan is in any way realistic.
