You don't always want the cheapest option. The cheapest shop that I went to just use air impact gun on everything and didn't follow Tesla's torque spec. He also didn't torque down the suspension at ride height which will cause the rubber bushing to be in a constant state of stress. It's hard to torque the bolts and nuts at ride height without a 4 post rack. You can do it with multiple jacks and safety jack stands but it takes quite a bit longer. You'll also need an alignment right away since a lower ride will give you more camber which will give you a ton of toe out.
