Just like you said the list is not complete as there are hundreds out there.
If you categorize them you might be close to the completeness. eg say Web hosting providers as oppose using the general word Technology services list.

The list needs to be categorized based on service and industry and do justice to the list otherwise you will be accused of being biased.
