I would recommend seeing if you have a local reef club nearby and seeing if someone would be willing to come out and help you get started. I'm betting you'd be able to find someone that would do it for free. Worst case, I'm sure they'd do it for really cheap. I've never used a company to do maintenance on my tanks, but I'm not sure they'd want to tell you everything a fellow hobbyist would. I mean, they make their money doing routine maintenance for people.
Yep, the stuff under the tank is where your sump is. It's pretty common. So water overflows from the tank down to the sump where all your filtration is, then gets pumped back up to the tank. If you take a picture of all the equipment down there, we can tell you what it does.
Just right off the bat though, water evaporates but salt doesn't. Unless they set up an auto top off system, you might need to start topping off the tank daily with fresh water. Also, look into getting an RO/DI unit if you don't already have one to use for top off water and mixing up new salt water. Buckeye Hydro (they sell RO/DI units, replacement filters and all kinds of extra stuff you might need) has been a big help to me and they're a sponsor here.
An engineer? Oh boy! I have engineer in my title but I'm in IT so I'm not an actual engineer in the typical sense. If you're like me and like to geek out on things though, you're in a world of hurt with this hobby hahaha. There's so much to geek out on!
