help gizmo get treatment for his seizures

hi, I'm angie and I'm fundraising for my kitten gizmo. I saved him from a barn. He was a runt and to young to be with out his mom. I nourished him back to health and when he started walking potty trained him and introduced him to his new brother. He seemed perfectly healthy and started to play, run, and jump. At about 8 weeks he started having seizures out of the blue for 30 seconds to two minutes. I took him and what money I had to a clinic in town and they sent him home the same day saying that it was toxicity from flea shampoo with out doing any bloodwork or prescriptions or much of anything saying it would ware off. The seizures continued and on November 20th he had a seizure for 45 minutes and now I believe he is blind. He's scared and sometimes doesn't even realize its me petting him. I'm 7 months pregnant and work part time at a fast food restaurant, I can't afford to get him the treatments he needs. I know if he can get to a professional vet with experience who will actually do bloodwork and get his seizures under control he can live a happy healthy life. I don't know what else to do, he doesn't deserve to be put down because he wasn't rescued by someone wealthy.

His name is Gizmo, he's 8~9 weeks and lives in Fremont,Ne.
