In any negotiation the main factors are power, information and time. Does the client have the power to get someone else to do the job or does he need your specific skills and experience with the code? Can you do other work and just walk away if you don't get your asking rate? Knowing the rate your friend charges is good info and it would be good to know what any other client employees/contractors make and also what general rates are available from other employers. Time can help - how soon does the client need the work done - can he afford to hire and get someone else up to speed? Can you hold out for a higher rate or do you have living expenses to pay etc?
