Script Request-auto silk buyer and seller

This could make alot of money. If you have 1m, for example, you could buy 500k silk in that place near the desert (sorry i forgot the name). After you sell all that silk in East Ardougne for 60 each, you'll have 30m. Do it again and you'll have 900m. I'm sure no one really feels like doing that and it would take along time. So please i'm requesting a SCAR scrypt for that unless there is one already. Could you also tell me if you make by sending me a message?
