E-Gold game modification

I have e-gold Batch script but it needs some improvements: 1) referal contest feature 2) special bonus: e.g. if batch number ends with 99 - 300% if batch number ends with 88 - 250% 3) Admin area where odds can be changed, statistics, etc. 4) Should be not only e-gold, but also webmoney payment gateway integreted with the same automatic deposit/payout. 5) Nice index page for this game. (optional price with and without it?) 6) Improved security of script. As I said I have script without those features, just need to improve that.
