Haha ..thats a bit random....amm what kind of job? If your moving to the north and its just a general job www.jobcentreonline.com
is the local site for jobs, theres the odd horsey one but mostly shop/office work. One that's good for horsey jobs would probably be www.yardandgroom.com
Others just of the top of me head would be ... www.jobs.ie www.monster.ie
Another site would be www.gumtree.com
(north) and www.gumtree.ie
(south) its one of them sites that people sell stuff on but theres a section for people listing jobs available, or you could put an ad up for yourself saying your moving here and you want a job doing... whatever
... hope this helps! Where abouts are you moving to? You have to come visit Derry!
