Byron was bitten by a brown snake

Byron is currently at the Thornlands vet hospital. They have told me he has been bitten by a Brown snake and is highly venomous. I have asked to go ahead with the treatment becuae I would be absolutely lost with out my baby. They have quoted between $3000-$5000 depending on how he reacts to the treatment. I'm asking if anyone would please help me fund the treatment for Byron xx
