"Don't you think Geotech will do initial interpretation of new data?"

No, their business is to provide the data, not to interpret it.  There could be a perception of bias in doing so, and it is, I think, illegal for them to offer both services.  Having said that, they have offered classes in how to interpret ZTEM data.  Usually, it is in conjunction with mining conferences in Canada.  I think it is 2-3 days, so is not a popular course in a convention atmosphere.
