Looking for a Shop to Rebuild Toyota Engine (SOCAL) [[HELP!!]]

Hey there guys,

So my grandfather pulled one of the big no no's and without telling me or any of my younger siblings he was taking his 2009 Toyota Camry to a janky side job oil change shop (not one real mechanic in the building) to have oil changes and what he says were"tune ups". Needless to say the work was done incorrectly his oil filter fell out while driving and the car completely drained all its oil. My grandfather is 83 so he didnt notice any problems until it was too late. Engine is now toast and I am looking to find any reputable shops that specialize in Toyotas or engine rebuilds in the southern California area. As of now he says hes got it at his "Guys" shop and I told him that I do not want anyone else touching his car until I do research on a well qualified shop. Wanted to see if any of you knew of any good shops I can look into getting quotes from. Please let me know!!! We are looking to get his car there ASAP.
