I am wondering if anyone knows of where I can find a script or coding to produce a graphic editor (something like the page I typed this message into)that I can place on my website so that visitors can create a basic layout to be used for a custom signage layout.(A vinyl banner for example) For example they need to be able to pick things like size, colour, fonts and place a custom image into, as well as be able to save and send the finished file to either my email or FTP server.
I hope you can help me out.

Thank you!!!
