Found a quick list from a dealer:
http://myhyundai.automaxhyundainorman-ok.com/norman-service-schedules/2014-hyundai-service-schedules/2014-hyundai-sonata-service-schedules/Air Filter - you can easily DIY, it takes a couple of seconds once you locate where it goes. I'm sure a place like AutoZone or similar would probably either install it or show you how to if you ask and they aren't that busy or just YouTube it. Cost - $15-20
Climate Control Air filter (A/C filter) - YouTube this, tends to be an easy change, but might be a bit hard to find. Mine is behind my glove box. This is a DIY fix. Cost - $15-20
"Inspect Everything" - this should be at most 30min or inspection. Shops around here charge me ~$80/hr, so $40. Tends to be free if they find an issue and you get it fixed from them. Some will do this for free/cheaper if you also do the oil change with them (since the car will already be up and easier to inspect) so just ask. Cost - $40 or less
Oil and Tires - this is a normal item. Either DIY if you can or just ask for a tire rotation at your next oil change. Cost - normal oil change (look for coupons!)
Not on the list - wiper blades - I personally replace these when I replace the air filter. Another $15-20 (for mid-tier blades). Once again either install yourself or ask an AutoZone guy to do it for you.
My advice - replace the 2 air filters and wipers yourself first (they are easy). Call around and ask for an oil change, tire rotation, and 30k mile inspection. If they say anything about the air filters or wiper blades needing to be replaced - question everything they tell you and ask them to show/prove to you why something needs to be done.
Last thing - keep all receipts for everything. The Walmart receipt where you bought the filter - keep it, any inspection reports - keep them. Never hurts to have this info - plus if you private sell your car in 8-10 years, these records show the car was maintained and you can get a better price for it. I have a ziplock bag in my glovebox where I keep all these.
