I'm thinking about getting surgery or something for facial asymmetry. What would help and the cost? (photos)

Your asymmetry is very slight and you would do best with a small amount of filler in the left cheek if the photo is accurate. No surgery!

Yes, you do have some facial asymmetry, but everyone does. If you feel the cheeks need to be more symmetric, then perhaps fillers are a good choice.

Best to seek a 3-D catscan of the facial bones to see if there is a reason for the facial asymmetry. Than seek IN PERSON opinions from cranial facial surgeons...
