Can anyone tell me where I can find a iPad holder kit  for standard 3 but I don't want to drill any holes.  Thanks

I am guessing that the RC for the Standard and Professional are different?

Here are some quick links for you:

While the most sturdy option would be installing the Inspire 1 tablet holder (like this), you can find some commonly used semi-permanent mounting options here.

There are 3rd party ones that might be usable without needing to drill holes:
