I was asked recently:
“What it would take to break into a business that I’ve never had the time to work in before because of the career field I am in?”
Often, all it takes is telling people your story in a few sentences. For example, if your prior job required you to be on call 24/7, you may not have had the time to take on a second job to break into your ideal chosen field. In a cover letter to an employer, you could explain this as follows:
“I’ve been interested in pursuing my career in XXXX, but until recently when I left my job in XXXX, I didn’t have a flexible work schedule that would allow me to test the waters. Now that I have moved on to a new opportunity, it is my desire to work with you on a part-time basis to bring my skills to your location.”
At the very least, you will get a chance to talk to this employer about the opportunity and demonstrate the honesty that most companies will value.
