anonymiss you really need to do your own market research and see what you feel is missing in the market and draw up a business plan. Plucking ideas from the air or in this case the cr room will only cause confusion.
A succesful business needs to provide a service not already in place. You also need to bear in mind we are in a global recession and people are not looking to spend money.
If you’ve got this idea into your head, why don’t you first do a course of some sort to get you more into the right frame.
Very best wishes and good luck to you.
