I was in a situation like you - but there is hope!
I did an IT degree but my first job out of uni was in new media basically as an input monkey. I really wanted out, but with no experience I couldn't get an IT job that wasn't ridiculously low in pay.
So I jacked the job in and started up my own business. Was ok for a while, but the competition was unbeleivable. The amount you had to spend advertising was very hard to recuperate from the work you're doing. It was around the time that everyone, even BT were advertising, plus PC World put out a big push on their clinics.
I had a loan and other nessecary expenses, so to ensue I had enough at the end of the month (£400) to cover them I took up a part time job just doing admin for a local civil service.
There was a local office IT guy there who I got on with quite well. He was leaving soon and recommended me to the IT manager as a replacement. He came down and met with me and decided to take me on a 3 month rolling contract to replace the local IT guy who left.
From there I've become permenant full time staff, I've worked in several offices around the county and left my mark wherever possible.
The only problem was I couldn't break into the central IT department (where the money is!) as most of the people who worked there had worked for the company for 20+ years, so they're there till they retire, which was longer than I was planning to stay as a local IT support worker. I got plenty of opportunites to do more technical work, however my big break came last year. They got a new communications manager, and his grand vision was to improve the internal and external communications within the company.
So before they went to a consultant, the IT manager asked around if anyone thought they could do it. That was my opportunity. I worked evenings and weekends learning all about sql, php, and web servers and how to get it all running, and the end result impressed everyone at headquarters.
In the end I had to threaten to leave before they decided they could spare the budger to give me the job I deserved at the central IT department. But it all worked out ok in the end.
Since then I've got involved with loads more projects and work closely with the companies senior management. I do the majority of IT purchasing for the company I even have my own government procurement credit card.
More recently there has been a shake up of the pay structure which meant my job role got a payrise when they considered all the things I manage and am in control of.
So, to cut a long story short, thats how I managed to get myself out of a dead end job into the job I'm doing now. At no point were any qualifications considered or required. The fact I could do the job was far more important to the people paying me.
