Making money as an arms dealer

After picking up a cheap blueprint (a DRMed copy of course) I am now an arms manufacturer and dealer in EVE Online.

I read that making money from selling self-manufactured items was difficult without Production Efficiency skill of 5 and I’m managing with 3. Although I’m not buying all the raw materials though. I buy the Tritanium which I needs loads of and mine the Nocxium myself. I think if I had to pay for the Nocxium then I’d be screwed…
