wysiwyg for oscommerce

I have a decal store online. I need to add a function to Oscommerce. I would like a wysiwyg editor that will allow the customer to input text. -Default text and font for each item -User to select size, font, color or texture of decal in wysiwyg -Any of my 100's of fonts to be selected, even if not installed on the user's PC -Ability to not allow the customer to change the default text or font, only color/texture on certain decals. This would be for dingbats. -Set avaliable in stock colors and textures for all decals and backgrounds. -Able to limit amount of lines for a decal -User can set decals size in inches or cm, which would change wysiwyg's size, and scale font sizes -Font size displays in inches or cm -Button to auto-fit all text to size of the decal -Italics, bold, underline, sub/super script -Background color/texture change of decal/wysiwyg editor which would also change the background color attribute in oscommerce inorder to charge extra -Background to default as checkered transparent bg, unless set for each product. -User's input dimentions change sq inch or cm attribute in order to change the cost (option which can be turned on/off for each decal in admin) -Able to set default dimentions of each decal -Button to display or hide grid showing measurment grid lines on the decal. -after pressing order, and the item is viewed by going into the cart, the wysiwyg should have everything the customer had ordered now defaulted for that item. if a second item is order, but color, text, font, or any attribute is changed, it must be listed as a new item, not add to qty of already customized decal.
