Not all accessibility checking is best done with "Accessibility Checking"
software - the most common package I know of that can give you and idea of
how complex your text is and propose at least some simplifications (via
grammar checking and thesaurus) is MS Word - this for Priority 1 checkpoint
14.1 - one of those that Steve suggests has very clear benefits beyond just

And there is quite a lot of software for checking different aspects of
accessibility - a list of some is at http://www.w3.org/WAI/ER/existingtools
but be aware that there are new packages or improved versions appearing at
the rate of one every few weeks to my knowledge.

  The costs involved in putting alt tags on your images are very minimal.  I would say a few hours at the very most for 200 images.  The real issue is the costs involved in making your whole site accessible.  And this would depend on your site and how it is coded now.

  Currently, I donít think there is software to test your site for a complete list of accessible issues.  There is software that will help you try though. http://www.cast.org/bobby/

  One of the benefits of adding Alt-Text to an image is that it enhances
  ability to automatically transcode HTML into WML.  This is a business
  benefit to those wishing to make their HTML content accessible to
  Internet appliances.  We have demonstrated this in practice.

  Simplifying the content of a web page has holds the potential to cut
  language translation costs in-half because, on average, you reduce the
  number of words by a half.  We have demonstrated this in practice.

  Simplified English is easier to read by those using English as a Second
  Language. This has been demonstrated in practice.

  There is more to the "value equation" of changing Silver [HTML] to Gold
  [Accessible HTML] than simply the cost of conversion.  Gold is worth
  than Silver.  To make good business sense your model will need to factor
  this value... whatever the business community deems it to be.  I can
  certainly provide you with my opinion. :-)  I predict that that the true
  "cost" is negative... to a great extent.

  Good luck on your efforts.

  I am wondering if anyone here either has or knows where I can find
  that provide figures (based on real or assumed data) around the time and
  cost associated with making a web page accessible?

  For example, given a web site with 200 images, how long, on average,
  it take to create the alt tag and test it? Additionally, how much
  additional cost does this add on to the development of  a site. Another
  example would be: how much time does it take to run a checker/repair
  on a typical web page?

  Any help in hthis area would be appreciated.
