Greetings,
I have read Project Description & understand that you are looking for only UI of App, so please send me NDA, I can then sign it and send you back for your approval.
Of course, our Designer's team can give you a very creative UI, so 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 finalize it.
Look forward to hearing from you and talking to you further thru' Freelancer private message board.
Regards,
YK
