@Valerie-Light Ok. I would ask if they need to be exported as separate Pantone spot print plates before you get too far. I would ask how they have printed in the past too just in case they have a way of doing it you can use as reference.
As far as I know Procreate will export to CMYK. So even if you use the spot colour refs in the file you will only have the four colours channels to make the print plates out of so no matter what colours you use it will only export to Cyan, Mag, Yellow and Black.
If it's 7 different Pantone print plates (which is a lot!) then thats quite a technical file to set up. If it's just use the colours and print as CMYK then that's fine.
The only way you would be able to get around this in Procreate, off the top of my head, is to use each colour on a separate layer and export that layer one at a time so they can make the separate spot colour plates. (Imagine it as if you were making separate screen printing screens.)
You would need to specify the order of your layers (which Pantone is the top layer, which is next etc.) make sure the colours are printed in the right order on the press (i.e the right colour is printed on top of the correct colour).
The best thing to do is let us know what they say.
