For this all you need is high level enginerring.
1) Buy a stack of saronite ore.
2) Find a miner to smelt it into bars or smelt it yourself
3) Make saronite razorheads
4) Go to the ah and post all 5 of the razorheads
5) Profit!!
This may or may not work on your sever, depending on the price of saronite ore. On my server a stack of saronite ore is 14-16 gold. The razorheads I can sell for 8-11g for 1. In doing this you will make 26-38g profit.
