how can i insure that the lawyer sticks to price decided in beginning and works as promised. (a business idea ):

Dear Sir/Madam,
Most common people has bad experience in dealing with lawyers and i
also face the same situation after fighting the case in high court. In
case the judgement be very adverse to me, i will also have to take
this same case to supreme court. The dilemma i face in such  that case
is that how i insure that the lawyer sticks to the rates decided in
the beginning and work as promised. Can you suggest some mechanism for
this purpose. I asked a bank manager for something internet-banking
equivalent to joint bank account in which if i deposit the full fee
then  he can withdraw it at the end of case only if i feel that he was
honest in his duty else i will also not be able to withdraw that money
ever. He suggested me a postdated check which i can later cancel if
lawyer turn nasty. But in this case lawyer may not trust me because i
probably have less cost on me therefore i was looking for something
like paypal of ebay or online joint account that be convenient to
work-out also.

If no such mechanism exist then i am planning to take agency to create an ebay like modality to hire lawyers online, it shall not be defficult because we have to arbitrate purely on the basis of clients satisfaction.

thanking you
sincerely
