First of all, that is an insane price for a small deck. If you just want basic pressure treated lumber, you should shop around. (My best guess is $5k-$6k.)
In my old house, I put down a bunch of these 16" square pavers and it made a pretty nice patio in the back. A smart person would use sand to level everything but I just tossed them down and they did the job. They are pretty heavy, you'll have to carry them one by one.

The other big question is if you need any stairs going from the house to the patio. If you do, a handyman could probably build you some pretty cheaply.
