I got to 40 in two days, and end the end I made a profit. Setting up on the right moon, having a little bit of luck, and not worrying about losing gil you could do it in a day.

Taking some time to research your market and to use your mules to buy materials and sell finished goods, you can do it in two days with profit.

I'll list the route I took, but every server is different.

0-3 Copper ingot. Sell at AH for profit
3-9 Brass ingot. 6 level gap so get advanced guild support. Save ingots for next stage.
9-11 Brass sheets. (use ingots from previous stage) Save for next stage.
11-13 Brass scales. (NPC for loss) If you run out of sheets to turn into scales, get advanced support and move on to the next stage.
13-15 Silver ingots. Buy beastcoins at AH. Keep for level 24 stage
15-20 Silver ingots. Buy ore from guild. Save for stage after next.
20-24 Brass Hammer. Buy bronze Hammers from NPC in Bastok. Sell to NPC for loss.
24-31 Hiraishin. Sell on AH for small profit or to NPC for big loss
31-33 Silver Chain. Sell chain on AH (slow), or to NPC for big loss.
You can now sell any left over ingots.
33-35 Mythril Ingot. Buy beastcoins at AH and sell for small loss.
35-40 Mythril Ingot. Buy ores at Airship vender. Sell for good profit.

All of the ingrediants it takes to get to 40 are always available. So If you got the gil you can do it in one day. Or if you have to wait for things to sell at the AH (like me) you can do it in two days.

If you wanted to get to 50 it would only take another day with unlimited funds.
40-43 Mythril Chain
43-47 Mythril ring
47-49 I did silver bangels, silver beast coins are hard to find.
49-50 Gold ingots using ore not beast coins.

This stage took me 2 weeks because all of the synths except for Gold ingots are a loss.
