Happy New Year 2018!
I have read everything carefully & consulted with my 2 senior team leads & developers, so I can give you our team high level understanding paragraph to make sure that we are both on the same page in terms of requirements understanding but my main concern is that our team estimate coming higher than AUD 750, as this is very low budget as compare to the overall features required for this project, so not sure if you can be flexible in it. No doubt, there are many bids within this budget range, as every bidder want to get this project, because on Freelancer website, whatever budget you will select to post the project, mostly people will bid within that budget range, no matter what actual working hours or cost it takes to develop. So, if you're flexible in your budget, we can surely talk about it more in detail, if not, then I totally understand and I wish you good luck.
Please ignore the bid amount, as our estimate is high & I would like to discuss.
Look forward to hearing from you & start further discussion thru' private chat.
Regards,
YK
