If youve done all the payroll, employee tax NI etc then all the accountant has to do is your own net profit and loss, same as a one man band.
I have a franchise set up, so I dont get involved with franchisee accounts, but its the same thing from the accountants point of view - I record all my own earnings and all the royalties I receive which is my income, then all the outgoings which is my expenditure.
My accountant tidies it up and submits it online - the Revenue prefer it that way. I pay 200 plus vat.
Some years ago I was using another accountant who charged me 2000
Do what I did - shop around.
