Hello!

This is actually my first time posting here but I have lurked around for a couple years now. To the point now!
I am looking to getting into a networking or pc support position, Currently I live in Dallas,TX and am a installer for time warner cable's business class. So, daily I come into contact with many companies seeking help with maintaining, and configuring their networks. Usually their server rooms are a complete mess of spider webs cat5 cables and nothing works. Usually when the "IT" guy is there waiting for me to finish their new cable modem install I ask for their advice. My question is.. given my current job and experience as a cable phone,internet and tv installer. what is the best route to becoming a applicant in networking or pc support? Before this job i also did help desk for a DSL provider for 2 years. So I am familiar with computers and basic networking. Currently I have read a couple a+ books but I have not taken any test to get certified. The "IT guy"s usually tell me to just get my ccna and I will get a job. That sounds a bit far reached for some one who doesn't have any college degrees or certifications. I really would like to find what could be the most logical route for someone who doesn't have the time or money for college.. Thanks!
