I actually figured this out, except i was using barbed tails. Ive found a very helpful guide on gamefaqs which lists the exact amount of components needed for every weapon and how much Gil you need.

I have three weapons in their final form, 3 Traps and 5million Gil so i'm not far off. But i really have no intention to farm for Dark Matters, i might just stick with farming sacrafices for perfumes and buy dark matters. It may take longer but it requires less effort
