Are there any agency owners on here ?

If so, do you outsource your link building?

I’ve just set up my link building service and have been contacting a number of agencies to offer a link to show what I can do, but I’m just curious about how many agencies as a % outsource as opposed to use someone in house, to see if I’m wasting my time.
