Hi Sharonp
We used Fore enterprises who are based out in fore, incidentally. Found them very good have had no hassle with them, they drew up the plans did them to the way we wanted and made whatever changes we required without any fuss, they also submitted our planning and we are using them to supervise the build as well.
There are a few architect around mullingar, i am sure they are in the golden pages but i have no knowledge of their work.
pm if you want fores number
by the way i have no link to fore just a satisfied customer
