Did my Chartered Accountant charged me high to file my income tax?

i had not filed my income tax since FY 2008-2009, i also had freelance income of about $12000 extra apart from my monthly salary of Rs 30,000.I contacted a CA and showed my bank account statement for three years, after reviewing the statement he said he would charge me Rs 80,000 to file for 2008-2009 and 2009-2010 including the tax amnt.I bargained and at last he is willing to do it for Rs 50,000 which includes tax amount, advocate fees, consultation fees etc.Did he charged me right? I have alredy paid him 35,0000.Till now he has only sent me an email with ITR 5 form with essment year 2009-2010 to sign and have sent him back.I would like to know how can i make most out of my CA.What are the other doents i can ask from him? Whom should i ask for my form 16? Please, educate me?
