Hey there! ^.^

First of all; welcome to FFXIV! Always glad to have new folks joining to keep this game alive. If you ever need any more help than in this forum, you can always feel free to add me in game as a friend or whatever; I am a mentor and I actually enjoy helping folks; I play on Crystal | Malboro.

Anyways!

I hope I understood your question properly? I took a screenshot of my screen to show you a level 71 FATE, which is what I'm assuming you're looking for in order to obtain seals.
I would suggest you get these seals, and rank up in your GC so that you may eventually be able to do 'expert turn ins' for provisioning which gives you a greater amount of seals.

Since you're looking for level 71+ FATEs, I suggest you grind in ShB locations for your seals ^.^
