I'm trying to do something kinda unique. I own a web design company, and I keep running into a problem. Clients have ideas and layouts in their head, but they have issues conveying them to me. I want to make a site like https://moqups.com/#!/, but have layout templates that they can edit. When they're done, I'd like them to simply type their name and the pages name and hit submit, sending it to me someway. How would I go about doing something like this? I want it to all be on my site, where they'll also pick other aspects of their site (color pallettes, stock photos, etc..). I already have a system developed for this, I just don't know how to edit text and make resizable elements with the canvas element.
