Greetings,
I have read Project Description & checked the attached PDF document to understand the overall flow.
Even though, we really need detailed requirements, some high level details of all the features but keeping the current scope of work in mind, I am afraid that our estimate is higher than AUD 1,500, because conversion from AUD to USD is also needed, which gives low rates in US $.
So, please drop me a message thru' PMB and let me know, if you are flexible in your budget, we can then surely move forward, as our current bid is just a placeholder since Freelancer requires to submit the proposal but once you respond us, we can then finalize it.
Look forward to hearing from you and talking to you further thru' Freelancer private message board.
Regards,
YK
