If you have an idea which somebody is willing to pay  to  expand it, then you are up and running. Your sale-able idea brings all funds you need. Your idea must be on the money, as people in the financial circle would say.  There are hundreds of examples. 

If you are a university lecturer you have an alternative. You can convince  the granting bodies that your idea worth investing in it. When the idea is mature enough you spin it off and start your business. Very many university lecturers go this way; specially if your research is experimental. No open door for those whose work is mainly theoretical. 

There is no "cold" start.

Thank you Dr. Ysseri,

Thank you for your suggestion. Here I want to express my self for clarity.

I am an expert in 'Project Management' 'Construction Management' of power plants, steel plants and some process industries. 

I can start my owne as a consultant, contractor or a builder.

I can do more than the expectation if I share with like minded people in expertise as well as investments.

If anybody in this group are likeminded and having resources we can think of it globally for mutual benefits.

It is required for me because I am doing research in basic and theoretical physics which may not be supported by funds.

Also I don't want to beg for funds. So it is required to search for my own development for the sake of my own research.

Some people may be interested in developing new generation in research but They may not be in a position in support. Such people may create their own money for their own ideals.

That is the main reason I posted it.

Welcome to such people.
