Hard to recommend because any cheap car wash will damage your paint in some manner, and the good detailers are overpriced. So depends on what your comfort level is with car washes. If you don't want to do it yourself, then I recommend finding any touchless drive through wash (there's a Chevron off Balboa Ave/I-15 that has one), and use your own microfiber towels to dry the car. The paint quality on teslas is already terrible, so you don't want just any dude using any towel on your car or running it through a wash with harsh brushes.
I opt to wash my own car for this reason. Chemical Guys has alot of great products and resources for a great wash/detail.
