The American Training Net website has developed a RFI - Request for Information - service:
"Looking for the right solution to your Training or HR issues? Then, look no further than our PowerRFI mechanism. From a single form you can send a Request for Information (RFI) to the most respected solution providers in the industry."
This is rather more than a search engine. The user enters a query into a form which is then distributed to several of the training providers registered with the Training Net service, who are to consider the request and respond directly to the enquirer.
Could be a useful service, although many of the respondents are likely to be US based.
Alternatively, try the TrainingZone Topic Expert service!
