As a stop gap measure, we are using Google's custom search engine service.

At this point the design looks like this:
1) Service program containing edit procedures common across multiple transactions. One procedure per edit. Each procedure returns a pass fail indicator and an error message as the first parameter.
You may want to reconsider the 'first parameter is error message'
design. That's how I started out doing things. The extra overhead of
passing in error-related parameters every time doesn't seem like much,
but it gets really tiresome and IMO reduces readability of the code.
If I were starting from scratch, I would prefer the 'global error info'
procedure suggested by Scott's article "Writing Reusable Service
Programs"*, in particular the sections titled "Statelessness" and "Error
Handling".
