You might want to capitalize on your current experience and add the Finance education to it as a value addition. Not sure what you do currently, hence cannot suggest some options.
Have you also evaluated some additional finance courses which are more specific to some topics and will help you start on job quickly. Something like a diploma and internship combination?
As far as age is concerned - don't be too bothered by that if you really want to make a career in finance. Better now than never
