Answer:
individual contractor for Acme Solutions
Explanation:
In the scenario being described Nicco is most likely an individual contractor for Acme Solutions. This means that he does not technically represent Acme Solutions and is not an official employee of the company. Instead, Acme Solutions hires Nicco on a per-job basis when they need him to fulfill a specific job and/or provide his unique expertise on something. Which is why they require that he provides all the training material since that is the experience that they are hiring him to provide.
