Help please! Starting a Chocolate Making Workshop business

Dear members of the chocolate life,

I have been doing some research on starting a business related to chocolate in the South of Spain. I have decided that manufacturing and selling would require too much capital and time. I have two small children and need to have some flexibility in terms of working hours.

The idea of offering chocolate making workshops at hotels, bars and private residences seems more realistic and easier to set up including the financing side.

The area where I live is a very popular beach holiday destination especially in the summer. The rest of the year is still fairly well visited by matured couples and groups. Families come back at Christmas and Easter for a break as the weather is better that the rest of Europe.

Therefore my plan would be to offer at least two types of workshops one for children and one for adults. I would approach hotels, bars and cruise ships as I would be mainly targeting tourists.

I will be very grateful with any advice that you might be able to offer me.

I have also listed below some questions that have come up as I am trying to put together a business plan:

1. Should I attend a formal course to use that training as my credentials? Can I get away with practicing and learning at home?
2. Maximum number of people in each workshop? I am planning to do it on my own initially and hire someone else if there is demand.
3. I have some ideas for the workshops' content: brief history, taste cacao nibs, show them the cacao fruit, tempering demonstration (only in the adult workshop), truffle making (only for the adult workshop), the rest will be creative (dipping and decorating), the children's workshop might include chocolate painting. Any suggestions for easy but appealing workshops?
4. What equipment would I require to run the workshops in the most cost-efficient manner?
5. How much chocolate would I need per person?
6. Hiring the venue would mean that if I don't get a minimum number of participants I will be making a loss. Any advice on this?

Many thanks in advance for all your responses.
