Thank you for your question...
[Q1] If you have collected money from clients that has been paid to you in advance, then it is not a profit and loss account item but should be shown as payments in advance for future services within creditors.
You should only reflect in your profit and loss account the income relating to the accounting period and not cash receipts .. prepare accounts on accruals basis i.e. match income and expenses pertaining to the same accounting period. There is no creditors line within profit and loss account.
[Q2] You don't need a UK Chartered Accountant to prepare your accounts if you are happy with the competence of an overseas based accountant.
[Q3] This is a difficult one to answer.. it depends on how complicated your affairs are and whether you have adequate accounting records. You could be looking at at least £4,000.
I hope this is helpful and answers your question.
