How do I find a doctor to deflate my implant?

If your implants are indeed saline, any surgeon who does breast augmentation can deflate them for you. I do, however, agree that seeing someone boarded by the American Board of Plastic Surgery is the best way to go. 

Let us make sure we are talking about the same thing; You can't just pop your implants, you will need to take them out; this can be done under local anesthetic in the office in order to keep your costs down; then when you are ready you can get your breast lift and implant augmentation. The reason for this is that a popped implant is vulnerable to infection as the inside of the implant can act as an abscess focus.
