Yes, I have some advice, I'll start by telling you what I did. I had my mind set on going into high-tech for the same reasons you've described. I met with a startup that was bootstrapping his BI product at 2008, and convinced them to let me do sales & PS for them - for free, meaning I would only get paid if I sold the product and managed to sell some PS hours. In return they supplied training on their BI tool, naturally I had to learn a whole lot by myself - basic things that were then new for me - DB, sql etc, but I didn't mind since I loved computers since ever.
After a few months of not selling almost nothing (wow, great surprise) my funds were running low, but I was already a different person. I knew what is a product, I knew what is a DB and how to connect to it etc, so I've found a junior job at a Qlikview (another BI tool) PS company. I picked up QV very fast and became very good with it, and after one year at the job was already the company's lead on financial BI.
After this year I already had the technical expertise to get a job that combined my new career with my old career and became an IT economist, no longer a junior, in charge of migrating the organization's financial systems to SAP and maintaining the existing systems until the change.
My advice - just get in IT. Don't mind starting from the bottom, in the grand scheme of things 2-3 years of reduced salary is nothing. Look for a job in the IT of your field, for example, since I had financial background it was easy for me to get a job in financial BI, but I could get a job in any financial IT system as helpdesk, PS etc. To get this job you might have to get into a course or even learn some new skills at home after work.
