To be honest, it isn't really that difficult to do yourself...
Especially if you have something like this:
Oil suction gun10l of engine oil (for the engine, box and transfer case), 5l of gear oil (front and rear diffs) or just 2l for the rear alone, new oil filter and something to collect the waste oil in. The drain and fill plugs are all pretty easy to access, and if you give the car a quick spin to warm up, can be done in a couple of hours.
