Greetings,
I have read Project Description & understand that you are already using a custom plugin with WordPress, so can I look at it? Once we review it, then we can come up with our solution and precise estimate in terms of time & cost to move forward.
Please drop me a message thru' PMB to start our conversation, as our current bid is just a placeholder since Freelancer requires to submit the proposal but once you respond us, we can then provide you our precise estimate.
Look forward to hearing from you and talking to you further thru' Freelancer private message board.
Regards,
YK
