Community Builder Plugin Mods

NOTE: For Community Builder experts ONLY!!! Familiarity with MySpace-type concepts (i.e., profile customization) strongly preferred. I’m using the plugin CB Customize located at voodootools.de. This plugin allows members to customize their Community Builder profiles. I need the following things fixed or added: 1) FIX - Deleting background image for one item deletes images for ALL items. 2) ADD - Allow members to directly edit their own style sheets, as opposed to using the plugin interface (this gives advanced users a chance to really customize their profiles) without compromising security 3) FIX - File upload check routines may need improved security, including checking for allowed file extensions (gif, png, and jpg ONLY). Please provide quotes and timeline ASAP. Unreasonable quotes will be ignored. Thanks.
