As someone working 50%, I can relate. I answered more than 100 messages last year on LinkedIn from companies/recruiters interested in my profile, and got to the end interview part twice (the answer was always 'working half time is not possible for us', sometimes after wasting a few hours of my time...)

But I also got contacted by a recruiter that did a fantastic job. He found a company that was a great fit for me, and that had no problem with part-time.

My advice would be : answer everyone telling you're looking for a part-time position. It's long, it's difficult and it's time consuming, but it's not impossible.
