Custom-Made HTML5 project.

I have an HTML5 product that allows users to create a personalized and customizable mini site that walks the viewer through a guided tour. The users should be able to change the graphics, modify the text and record their own audio voice-over should they choose to. I have an HTML version and an HTML5 BETA but they are not quite at the level where I can release them. I am looking for HTML5 EXPERTS only. All text, graphics and audio will be supplied. The HTML5 framework is already done. All we need now is for the presentations to be editable by the end user. They should be able to change the graphics, change the text and record their own audio voice-overs. I'm also looking for a basic sales website that will promote and sell this product. I've included a link to the HTML version merely to give you an idea of what the project consists of. [login to view URL] The work has already been rewritten in HTML5 and we just need to add those three functionalities to it. Where the user can make changes to the code by changing the text, recording their own audio and changing out the graphics and including video.
