I would like to create Bidding or Tendering web site so that suppliers to a certain agency can be alerted of what is needed by the Buyer agency and the suppliers respond online. This assumes the Buyer organization Posts Bid Notices in the Press and they also post to the online site where the developers keep enhancing until they make the users to response efficiently. I have built the landing page and the grids listing the opportunities. A good example is that of the UN:
https://www.ungm.org/ and Kenya website. I have some extra information to share and clarify on the design anytime this week. I will provide any missing information where necessary.
