It's very easy.
I'm actually off in about half an hour to put in a laminate floor at friends house. It s simple. Just look at two youtube instructions video's, read what it says on the packaging and you're off.
Really, anyone who knows how to saw in a straight line can do this. Because that's the hardest part, getting the laminate to the right size. (And shape for some weird corners.)
I've done this in about 6-7 houses so far and every time taught the person I was helping to do it as well. Never seen anyone who was not able to put in a laminate floor. Just read up a little and you'll be fine.

The update some hours later. With 7 people we laminated a 3 storey house today of 120 square meters. Teams of 2 per floor and one person for food, beverages and garbage duty
They asked for a quote to have it done, 15 euro per square meter = 1800 euros or about 2300 dollar, excluding material.
Seems to me it's worth it, even if it takes you longer than it took us. (7 people about 8 hours each). But I didn't yet count the muscle aches that'll keep from doing anything tomorrow. Hauling all the stuff and working on the floor the whole time does start to hurt. If you've got any existing back problems, I'd probably advice against it.
