I think most organizations won’t provide a service dog to you unless you have a certain number of seizures per month or week. That’s what I’ve read on several websites that do provide seizure service dogs.

I volunteer for a Service Dog Organization that has many locations. I am a “ Volunteer Puppy Raiser.” (BEST job ever!!) But they offer FREE service pups for people with all different needs! Their website is caninecompanions.org

I’m also looking for a service dog. Where do I begin?

Try getting a hold of the Epilepsy Foundation ,in your state. They might be able to help.

It's dif per person, but as for the? I suggest getting people's opinions from here and then get some resources and referrals and then sit and do some thinking about what you have at your disposal and check out what you came up with your looking into and go from there , you should be able to get a few leads to tracking a dog down, good luck with doing, my opinion
