Do yourself a favor. Learn how to do your own oil changes. It's quick, simple and you don't have to worry about some dipshit putting in the wrong fluid, trying to rob you on things you don't need done, or damaging your vehicle because they are untrained morons.
I used to work in a couple of shops years ago and I was amazed by some of the morons they would hire to do things like batteries and oil changes. Many times people with no automotive experience lucky if they know what a box ended wrench looks like.
10,000 miles on your car, do you need to do a oil flush... no. I do one every so often on my vehicles, maybe around 50,000 or so. You do not want to flush the oil too often. When they use things like an engine flush additive it usually has a cleaner simular to kerosene in it, this is what breaks down teh sludge so it will flow out of the drain plug. Pouring this into your engine too often can dry up seals and gaskets which can cause them to shrink and crack in the long run.
However when I do need to flush a engine I do it myself and it costs about $10. Buy a can of 5 minute engine flush, and 4 quarts of cheap no name brand oil. Pour the engine flush in and let it run for 5 minutes (bet you didnt see that coming, lol). Once it's cooled a bit pull the drain plug and let out the old oil and engine flush. Then I pur in the cheap oil, run it for a few minutes, and drain it out. This makes sure you don't have any left over engine flush sitting in the back corner of the oil pan, in the lifter valley or anywhere else oil collects in the motor. Once all the flushing oil is drained I fill with a quality synthetic, my personal favorite is AMSoil.
BTW, if you are using quality synthetic oil you will have very little to no oil sludge to worry about in the first place.
