I have over ten years of experience building/repairing custom PC's and networks. I have been doing this on the side and I have come to the point where I have decided to make this my main career. So I began to get some certs. to back up my experience/knowledge. I currently have my CompTIA A+ and NETWORK+. My question is where do I go next?

lol Although I have had some knocks at my door, I have not been offered any good jobs as of yet. My question is, witch cert. should I acquire next? My choices are either stick with CompTIA and go for Security+ or move in a new direction and go for CCNA? Now I realize that these two certs lead you in different paths, but witch one of these two would help open more doors for me? Any input would be greatly appreciated. Thank you.
