$30 - $250

Project Description:
I need a finite sweepstakes program written that I use on a PC and print out winners and non-winners. For example:
4515 entries @ 1 credit = 4515.00
499.00 * 2 = 998.00
100.00 * 4 = 400.00
50.00 * 8 = 400.00
25.00 * 8 = 200.00
5.00 * 105 = 525.00
1.00 * 700 = 700.00
0.00 * 0 = 0
0.00 * 0 = 0
Prize Payout.......3223.00

Gross Profit........1292.00

Profit %..............28.6

I, as the administrator would like to be the only one with access to changing the different variables in the program...(Total entries, Prize payouts, Gross profit, Profit percent and Prize values)
The program should be able to print out a ticket that will be simple and have the ability to write message and time stamp when the entries were used. I need this program to have the ability to be used on multiple PC, but not networked.
I'm sure this type program has been written before so it should be an easy job. Please let me know if there is anything I would be missing that would be helpful.

Skills required:
