Aftermarket transmission coolers like the Derale Series 8000 # D13503 referenced in your question aren't custom-fit items designed for specific vehicles. As a general rule when picking out a transmission cooler you simply want to go with the largest one (for more cooling capacity) that is still small enough to fit between the grille and AC condenser on the vehicle. Most likely the Derale 8000 will fit perfectly on your Sienna but you will want to take a few measurements to make sure you have the mounting space available. This cooler measures 11 inches wide, 8-3/4 inches tall, and 7/8 inches deep. I have attached an image with these and some additional measurements labeled that you can also check out.

We do not have any specific recommendations for shops in southern California but we typically recommend simply finding a local independent shop or mechanic that has a good reputation. A transmission cooler install is a pretty straight forward process that a good mechanic shouldn't have any trouble with.

I have attached an installation video on a similar vehicle to your Sienna that you can take a look at along with the written instructions. You might even want to bring the installation details up to the mechanic in order to receive an accurate estimate.
