Ask if they or someone they know can use gas to put it under. It's better than injectables and they come out from being under very quickly. I've had it used for a tiny budgie with no problem.
Noticing where you are from, ask around for vets that will give discounts or are not too expensive. I'm lucky here as there is a great avian vet that is super cheap and knows what he is doing. Of course it's a long wait to get in to see him but for the price and expertise it's worth it.
