There is tons of possibilities of automation, but you have to split down general services delivery into underlying operational categories behind it, then you migh find relevant products/ case studies, if not then you have to dig deeper and decompose into smaller operational areas. In my case it was (software developement company) it was something like: frontend usability testing, frontend ux testing etc.

I would recommend decomposing and prioritizing:

  - what takes most of your time
  - what is needed to close the automation loop for a process

If you can eliminate small task and in return larger delivery process gets automated, then it might be more beneficiall then fighting on automating large complex process
