Hello Client,
Yes, we need to see the PSD first.
All depends on the design.
Because in Parallax everything is not compatible.
Hence, I need to see the PSD design to get the design structure and if required, I will be suggesting you to change something in the design to be compatible to parallax scrolling.
Need to speak with you more regarding the work.
Waiting to get few things cleared and start the work.
Regards,
SmithDGL
