Information is required to pitch a new business development concept to
the major
on line auctions.

My question is: I would like a list with complete contact details of
the key person(s) of the five top  internet based
auctions to whom a new idea could be introduced. The new idea would
lead to significant growth for the on line auction house. A generous
tip will
be paid if the answer includes solid text information on how a person
should go about making such a contact without revealing too much of
their new
brainchild.

Hello Brudenell,

Following are top auction sites with contact details. I post this as a
comment because the addresses provided are not necessarily the key

To your last question, it'll likely make the most impact if you visit
the office yourself to pitch your business idea -- also, in such
direct communication you can better control how much you reveal.
Good luck!
