Urgent - Small basic script to develop

we need a script which acts like a "scheduled countdown". Basically, this script will be used on an online salescopy for a product for which we can sell a limited number of units in a day. On our online salescopy (.html page), there will be a text similar to: "Live count: 90 Units Remaining - Updated at 7.30PM GMT, September 30, 2011" We need to be able to set from an "admin" page, the current time and the number we want to appear (as the number of "remaining units") at different set times. (up to 20 different set times). The script will have to display the programmed number of "units remaining" and the time of the "update" on our .html homepage. For example, let's say we input the following configuration in the "admin" page: "95" units at "8PM", "87" units at "8.30PM", "84" units at "9PM", "84" units at "9.30 PM"... What is between the " " is what we need to be able to set from that "admin" page. and the following will be displayed on our .html salescopy page. - Live count: 95 Units Remaining - Updated at 8PM GMT, September 30, 2011 - Live count: 87 Units Remaining - Updated at 8.30PM GMT, September 30, 2011 - Live count: 84 Units Remaining - Updated at 9.00PM GMT, September 30, 2011 - Live count: 84 Units Remaining - Updated at 9.30PM GMT, September 30, 2011 - and so on. The only dynamic values in that text are the "number" and the "time". Please note that the script will not be linked in any way to our order system. It just has to be a very basic script which displays a set number at set times. Important: This project is very urgent. We need this to be completed by tomorrow afternoon (Saturday) at the latest Along with your bid, please indicate which programming language you will use. (the simpler one, the better) Thanks for your bid
