I give priority to people who can get this done quickly. Please use the word 'chaos' in your application so I know you've read this. Problem: I live in Thailand. I need to call Australian mobile and landline numbers. I need an Australian Caller ID. I need Australians to be able to call me on this same local Australian number. Looking for the best quality. Someone referred Did Logic but I'm open to other alternatives. How do you propose to go about this? Are there any other programs you recommend? I'm looking to get this job done as soon as possible. Please propose to me how long it will take and how much it will cost. The cost I have placed on this job is not real - I am open to offers. Thank you, Jordan Hogan
