Dying Chair Cushion Covers?

[DALEPQ]

We have 6 new zippered dining chair cushions that we are looking to dye a darker color.
The new cushions are "Beige" looking to have them more of a "Rust" color.
They are a synthetic type material. The cushioning inside is removable.
Has anyone had experience in having cushions dyed??
We would prefer to have a "professional" service do this. Anyone know of this type of service??
Thanks in advance for any helpful replies.

If the new cushions have tags, I would do a search on dyeing this type of material, then follow-up with a review of YouTube videos. In any case I would have a backup plan in place if the dyeing does not work, like search Amazon, or equal as well as local shops for replacement covers in the color you want.
