Sounds like you need about 16 cubic yards of soil. That's roughly 1 dump truck load. When I was bringing in fill, it was going for about $250 - 300 per truck load (this was 2014). You do have to be really careful with fill. The vast majority of it is junk. With some searching, I was able to locate a really nice loamy sand (from Palm Beach County -- there's not much sand down here). I did send off a soil sample to a lab before buying it.

Look for a nice loamy sand, preferably something that's in its natural state. Around here, a lot of the fill sold around here is some sort of mix of limestone rubble plus muck plus horrendous looking mulch. Given that you're in an area dominated by sand, you shouldn't have too much trouble locating a good sandy fill.

You might want to hire a laborer for a day or two. Moving 16 yards of heavy soil isn't going to be a lot of fun. I ended up contracting a guy with a backhoe, but for such a small project, it the cost of doing so would not be worth it.

You're also going to need a place for the truck to dump the load of soil. If you have a strong driveway, they could dump it there.
