how to sell an idea?

[FauckU]

This is simple everyone,

I have had this idea for a very long time and I have wanted to develop it with a computer company like microsoft, apple, dell, etc. I know it could probably have a high potential selling in the market but I am not sure. However, I would still like to share with a company to see what they think..
I just don't have the knowledge, money or experience to develop it myself... I really need to know how to sell it or gain profit from it,.. I know this could earn me possibly millions!!!!!
I do not have any money to build this on my own, Im a college student in debt so I can't build a prototype or anything, please help.

I also know that I have to make a copy right before I even tell anyone.

So what I want to know is.. who do I contact? how would it work if I sell it? would they even share profit with me? would they steal my idea? Give as much info as you can!! please and thank y'all

If you wants sell online then publish classified for all products, in which mention brand details, which you are providing. Also mention price, you can add coupons for products.

It would help if you prepared a business plan outlining the market and how to reach it, timescales, investment required etc. That way it moves from being an idea to something valuable and of interest.

Unless you have industry contacts its unlikely to get you the needed face time with the big companies. So consider doing it small scale with a local company you can reach, then look at growing it from there. Look at getting a non disclosure agreement
