Help me Save my friend

As some of you may already know, my husband, Steven has been diagnosed with malignant metastatic Melanoma. This type of cancer has been historically difficult to treat because of its aggressive, quick moving nature. The cancer has spread to his lymphatic system. Steven has been through so much since he was diagnosed. He has been moving from one scan and test and surgery to another and these things are taking a toll on him and on our resources. The oncologist prescribed chemo/immunotherapy as soon as possible without delay - for the duration of one year. The cost is 91,000 Hong Kong dollars (11,600 USD) per treatment (every 3 weeks). He needs 9 treatments for the first 6 months. He's chance of survival depends so much on this treatment. I am desperate for solution. It's a very difficult situation for our family - especially for our 2 little children who have been seeing their dad becoming feeble. It's hard to believe this is happening to the gentlest and kindest man I know. We appreciate so much any help you can give us.
