There is a need for portal, which is called sms-auction.
There must be user side and administrator side.
SMS gateway is already set up.
From user side:
There is some auction, customer wants so buy some product and sends SMS "AUCTION1202" to some number. Bid for product go higher 0,0x cents.
In auction view, there should be: time left, how much bids, current price, is auction active or not, last bidder. Such data should be seen "live" - auction time left etc.
From admin side, there must be a way to define all former values. Also when the auction will be active, how long is time delay in auction after bid, product entering with pictures etc..
Simple user registration form - save to database and send confirmation email.
Please advise, if you have done anything alike before.
This in ongoing work after site is up&running.
