Timeline and Cost for Launching Advanced Project with Large Company or Small Business

If I want to open Advanced project with the help of high company or small buisness
how long will it take and how much will it coast . How can I talk to them face to face
How can I get them to hear my out.

Just a few houghts:
Among other things, study up a bit on business practice and patent law, if you don't want to get taken for a ride and robbed of your invention,.

It worked pretty well for Bill Gates.
------
Otherwise, focus on getting your electronics qualifications, then get a job in the industry, and see what's going on from the inside.
------
Read electronics magazines and websites, and do electronics as a hobby, and you will progressively discover what things can or can't be done, and you will also learn what's already been invented.

But is there an company or small business that can help me with that.

I don't even know which side off the world you live on, so you will have to do some legwork !

Prepare your CV. Google a bit of research on companies that do the kind of thing you are interested in. Company websites will give you the kind of work they do, the vacancies they have, what kind of people they are looking for.

Drop in on local electronic companies, ask what jobs they have, tell them what you have to offer.

What qualifications do you have now, what are you studying, what specialisation do you intend to go into ?

I'm don't have qualification I'm not trying to look for a job in that type of companies I just want to work with them as a business men. And how long will it take to get thinks moving.
