Greetings,
I have read Project Description & understand the overall scope of work, since it is already developed website, so our team definitely need some Man-Hours for understanding the existing code. So, keeping al the requirements in mind, our estimate is higher than AUD 1,500.
Please drop me a message thru' PMB and let me know if you are flexible in your budget.
Our current bid is just a placeholder since Freelancer requires to submit the proposal but once you respond us, we can then finalize it.
Please check out our Freelancer profile https://www.freelancer.com/u/leadconcept.html, as we have delivered many successfully projects lately and let me know, if you want to see some of our recently developed projects.
Look forward to hearing from you and talking to you further thru' Freelancer private message board.
Regards,
YK
