Prospective job hunting

I’m a qualified secondary school teacher and I’m currently teaching in England, however, I am registered with the Teaching Council. I’ll be coming home for the Easter holidays and I’m trying to find a job in Ireland so I can relocate back home. One of my family members had the idea that when I’m home over Easter, that during the 1st week of the holidays (when Irish schools are still open) I should personally call in to schools with my CV to enquire about any potential positions. So I guess my question is, would this be useful and have any chance of helping me get a job?
