How to Change Careers into Technology

For the past 10 years I've been working in government and public relations, but my passion is in technology. I'm 32yo and I've built a consultancy in my spare time that is very tech heavy, but it's still just a one-man-show. I would like to get a full time job in the tech industry, but I'm not sure how to do that as someone whose resume only shows non-tech achievements, jobs, etc. What should I do?

Possible suggestions from others:

1. Get an adult internship; Find a company willing to take me on for free or low pay to get my foot in the door. 2. Get certifications. 3. Lie and stretch what I already do into something more tech-centric.

I can't afford option 1. Option 2 I could do. Option 3 I think has more pitfalls than positives so I'm avoiding that one for now.

Any thoughts or suggestions?
