E-Gold Game Virtual Stock Market Script

I need to create an e-gold game that I can manage witht the click of the mouse very easily. It is a virtual stock market game with about 10 to 20 stock options all of which are made up by me. I need the ability to manually but easily set the prices of all the stocks and change them around anytime very easily. Also whatever the price is at the moment I want people to only be able to purchase it at that price and along with that I want them to chose the quantity of the stocks they wish to purchase also they must pay a 5% commission fee everytime they buy. So basically... .. . I want them to buy stocks at the given price that it says, maybe next to the stock it will give option to buy and at that price. I can manually change the price anytime easily! They chose quantity of stocks to purchase. They pay 5% commission. I also want a 2 part refferal system where people can get a 5% bonus from the deposits of the people they reffered and 3% bonus from the person their refferal reffered. Simple refferal system. If possible I also reallly want a graph. For example everytime I change the price I want the graph to show the price movements, this would be nice if you could make it. If you were bidding on my last project I'm sorry I closed it but my friend took over that project and I will be doing this one. I just want to get me a person right now but I will not need this for a good 2 months or so maybe more. I just want a person right now that can do it. My budget is not very high and I have seen familiar scripts without the graph for only $100 so I hope you don't expect me to pay far above $300.
