low cost accomodations fairly close to Dublin...

Am thinking about spending a month or somewhere in a SMALL town near the water, in a private home or guest house (peferably), I Am on disability, anything but rich, so I can't do the hotel/motel scene and that's why I am seeking a less expensive accomodations. I am only 1/4th Irish but Ireland is the only place abroad that I've wanted to visit at least once before I die - I have promised this to myself.
So, I am asking for some help in finding such a place - or is there one ?!?
BTW - I am a 54 year old female, VERY Quiet, a reader and a walker. I do not drink to excess - social only, really. Am a smoker (I KNOW!!!!!!!!) but will not smoke indoors. I pick up after myself and would be more than happy to help with any or all chores on day 3 till departure. Can produce a lengthy band of names for recommendations. Please email me at york051955 @ yahoo.com if you know of any and all possibilities of your findings. Your aide is greatful and I thank you in advance.
