If you qualify, you can avail of an audit exemption, in that case you could use a book-keeper to submit your accounts to the CRO.
If they are members of a professional accounting body or students of the same, that would be work considered to be public practice, which, if they do not have a practicing cert could get them disciplined by their body.
I'm not even going to comment on what happens if they make a mistake with disclosures or formats.
What do you think is a reasonable fee for this work?
