Why:
In a conventional marketplace, a buyer needs to search for products or services that he/she wants. So, how about allow buyers to notify their demands and automatically receive offers from sellers/suppliers?
How:
Providing an online website in which buyers can list their demands for products/services in a manner that they get automatic quotes.
What:
A website that implements the inverted marketplace, where quotes are automatic sent to the buyer based on his/her needs listings.
