I want to get my car service for the first time, how much is this gonna cost?

just 4000 miles

Technically by miles you're not even due for your first oil change yet.What percentage of oil life does your maintenance minder say you have left?... THAT said... mostly just a thorough inspection (visual) ,they should 'pull' the VIN status to check for any recent product updates (usually software updates on the hybrids),or recalls, if any. If you're in a dusty or high pollen area or park under trees, they might recommend an A/C cabin filter (ask to see it)and remember ..just like a vacuum cleaner it's the fine dust particles that clog the filter not the big easy-to-see chunks of debris. Tire rotation by about 8K depending on driving habits/road conditions. PLEASE read your owners manual! that will save you a lot of time and money!!! GOOD luck ENJOY THE RIDE!!!

Oil is showing 40%. Thanks a lot you reply really helped. Thanks :)
