Job Hunting Tactics in Ireland

So I've been living in Ireland for 2 months now and I haven't been able to get casual work of any kind.

Although I think I've been using all the most popular job websites and doing a lot unsolicited CV dropping, I feel there must be more I can do, considering I have strong enough work experience to cover many different types of casual work.

So that said can anyone help me out by listing some job websites or give me ideas of places I could apply as I'm going to be sh*t out of luck in terms of money soon.
