My 1st thought has to be a big congratulations on achieving your technical certs!
I'd like to discuss your self-promotion, and then secondly your skills.
So Let's focus for a minute on your CV / resume and your social media as these are both vehicles for self-promotion. There's an undercurrent throughout both - communication. As Mike has mentioned in both social media and also your resume, you will need to communicate and demonstrate who you are and what you can do. Take a look at your resume and your social media accounts and ask yourself "is this a good advertisement for me?" Do they show evidential skills?
Also build your social media network. Linkedin and twitter are great social media platforms for IT professionals. Start to post something meaningful at least once a week, and keep up the cadence. Your network will grow, but be careful with the cadence - set one you can keep because as soon as you stop posting your followers will tail off. Maybe start by answering some of Ronnie Wong's weekly networking questions on twitter, or replying to some of our posts on linkedin.
When wording a resume or social media page include achievements that can be proven and that demonstrate the skills required in the job advert. Research the company that you're applying to and tailor your CV and cover letter to the role. If the organisation's web page shows a dedication to Green IT or sustainability, ensure that your CV and social media profiles contains mention of a project you've worked on (can be voluntary) that shows you share a passion for sustainability. There's a lot of overhead in tailoring your CV each time, but it is worth it.
Just to re-iterate Mike's comment about volunteering; you don't have you limit your CV to just work experience.
Secondly think of your skills. You mention that you're a police dispatcher - that makes you an ideal candidate for a helpdesk role; a role that is often seen as a entry level role into the IT sphere. Make sure the skills that you've learnt as a dispatcher such as ability to work under pressure, strong communication skills, etc are highlighted on your CV.
All Helpdesk analysts now require ITIL certification, so take a look at the ITIL 4 Foundation course too.
I don't know if you caught the recent webinar on Helpdesk skills, CompTIA went on to create a blog out of it: https://app.itpro.tv/course-library/10-qualitiesa-help-desk-pro/10-qualitiesa-help-desk-pro/?tagcategory=course-library&tag=it-webinars
Hopefully I've given you a few places to start, but I'd be happy to answer any further questions, or even take a look at your CV if you'd like.
Good luck in your endeavours!
