I get the certifications for me, not for clients. I list them because I have earned them but I really don't think the clients give a 'durn' about the certifications; they just want to know that I am qualified for the services I offer to them.
I have lots of 'hands-on' experience with IT but don't offer it as a service. I will, however, jump in and assist when someone has an IT question that I can answer or figure out. I also have a tech guy that is my equivalent (an 'office god'

) when it comes to computer issues whom I consult on a regular basis.
