I'm working as an enterprise software developer. I'm quitting working as an empolyee for my current employer. We agreed to have a negotiation talk in the near future about me continuing to work for him as a contractor.

Basically i want to convince him that use me permanently sold to a customer of his (big financial institute, i'm currently working there) and make the foundation as being a permanent project leader there; because there is none and i see the opening. I want to convience him that he will save a lot of money this way in the long run which i can make a solid case for. If no such thing is available i'll search a job of such elsewhere.

How do i get into this talk? Do i just ask him hey what's your long term strategy with this client?
