The thing with these consulting companies is they will never say no (including for stuff that they are wildly unprepared to do). You can hire them for installing software on employees' computers, deploying and managing some SaaS product, building a healthcare signup website for an entire state, building an internal portal, running a tech conference, even planning a company picnic (not kidding). So trying to define what area they operate in and what exact role their employees play is impossible.
