Questions about virtual tour programs

Hello all,

I don't know if I'm in the right forum or not but it seems that
everyone here is extremely knowledgeable about computer programs
unlike myself. I'm looking for some help or information in regards to
virtual tours. I have a business idea and want to create a virtual
tour of my idea and present it to possible investors. The problem I'm
having is that all of the virtual tour programs that I've found seem
to be for companies that are in existence. Does anyone know if there
is a program out on the market that I can buy that's easy to
understand and where I can design what I would like the business to
look like from the outside and then make it where you can go into the
front door and be able to see the inside of the business.Well I just
want to add a little further an additiional info. that I have a
website of my own .Visit : http://www.gznetwork.net/main designed by
web designers at http://www.webdesigningcompany.net .Anyway Comin
gto the point ,It may also be way over my head to understand the
programs. If so what kind of company would I need to hire to create
the tour for me and what's a good estimate on how much it would cost
to hire someone? I may not be asking the right questions, so any type
of help is appreciated.
Thanks in advance.
