MS Word Add-In

I'm looking for an experienced developer who can create an Add-In for word that would, when activated, disable and/or restrict access to a list of features. These features would be primarily formatting tools and proofing tools. All formatting must be disabled except for a specific paragraph - in this case Arial, 12pt and Double Line spacing. All other formatting options must be disabled. Proofing Tools also need to be restricted - no Spelling, Grammar or Format Consistency need to be disabled. Ideally, the Add In would need a password to be entered before it could be activated. Not sure if thats possible though with an Office Add-In I'm currently the above with Group Policy, but need an option for non network devices. Something that a non technical administration assistant can pretty much do with a a few clicks. Please only bid if you can develop Word / Office add ins and extensions. DO not hesitate to contact me should you have any questions
