That's exactly how I got into the field: spent 2.5 years at home building stuff, and then published my CV on a head hunter site. That was in the morning and in the afternoon I started getting first calls from recruiters. But that's in Russia, and I also set my desirable salary quite low. But still, I ended up with my current company stealing me from another one whose offer I had accepted but hadn't started working yet, and my current company offered better conditions and it took just a week from the first contact to me accepting their offer.
