Appropriate fees of ca

I have a very small business. The total invoices per year will be not more than 40 in number. All expense and bank enteries will not be more than 500 in number. Total revenue is not more than 5 lacs per year.

I want to know what are the appropriate fees I should pay a CA to write my accounts, prepare Balance Sheet, P&L and Statement of Income and also file Tax returns.

Thanks in advance.
