My product is is an improvement to an existing. Do i take my idea to that particular company with my idea or do i file a provisional patent?

File for a patent to protect your rights.  To get a patent though, your devise will have to be a substantial improvement over the existing unit.  The patent office will make that determination.

speak with a patent lawyer - expect to pay said patent lawyer.  The "free" 1/2 hour consultations that are thrown around on this forum are worth what you pay for them.
