You dont need craftstamps for crafting D grade Duals
Just the 2 swords (you can buy them at Giran weapon shop) and bunch of D Crys (120 if I'm right not sure). Giran Blacksmith makes the craft for you.
For elven/artisan 107's you can get them made with the two swords, d-crystals, and I believe some adena (smallish fee).
The blacksmith in any town can craft those for you.
Do what i did yesterday...
Buy Delusion sword in Giran shop 6.500.000a
Find a topC grade weapon for 10M -
Find mammon and change the Top C to a SLS and the Delusion to what SA you whant for the Duels.. in my case Tsurugi.
Go to Aden combine them with 450 somethins SoP's
and a small fee of adena.
Get out and find cheap EWB, 4 of them.
Then enchant them to +4 so you get the SA
