Find a few shops that have good reviews and go visit them. See if any of them will give you a firm price, instead of X amount per hour. Id find one that will break it in and tune it as well.
Just remember, the more work you do, the less you have to pay them so you could drain the coolant, oil, etc, and disconnect the exhaust, fuel, smog equipment, bracketry, etc. Then have it towed over to the shop.
