How can I increase my goldsmithing craft from level 27 to 30?

[Canadianmonster]

I want to make mythril ingots, but I can't until I reach level 30 in goldsmithing. What is a quick and cheap way to increase my level. I have about $50 grand to spend, so I'm opened to ideas, to what I should make. I have already spent $100 grand making silverarrow heads on to increase my level from 25 to 27. So I know there has to be something better out there.

Please will someone help me!
I just wasted $30,000 in making Silver Ingots to Silver Chains, and I still was not able to reach level 28. In goldsmithing.

I just want to know what I'm doing wrong here, because I've wasted so much money, and I know their has to be a better way then loosing $100,000 for each level after level 20.

I'm not that high, but I think after Silver Hairpins cap out you need to make Silver Chains (huge loss) before you can make ingots again.

I doubt there is much profit in it but you can make:
Hiraishin(ninja tool)
copper ingot + silver ingot + fire crystal
should take your goldsmithing to 30
or
Silver Ring
Silver Ingotx2 + fire crystal
should take your skil to 31

fire crystals are getting cheap because of the new users from ps2 so it might be a good time to do these.
