why don't you just sell 180 cowhides at the al-kharidian bank for 100gp each, it will get you 18k then start buying things at low prices and selling them for high prices, get that 18k to 100k and start buying rune scimitars on world 29\1\32 outside varrock west bank for 20-25k each and sell them for 25-30k each until you get 200k then move onto rune 2h buy 45-50k sell 50-55k until you have 300k, then buy one set of full black (t) for 90k and sell for 100k, theres a nice 400k now keep merchanting until you get at least 4 mill. It's really easy i did this for a year when i was level 3 and made 96 mill (around there i'm leaving out the thousands) bought myself full sara and a white party hat then started training my combat, mining, smithing, fishing, and cooking.
