Measure the area. Find the pavers that will fit your measured area. Lay out the area with a spray paint or ??? I would use tools to dig the area out shovel, pick ax with a 3-4" blade or??? Dig at least 12" deep. Add drainage stone 1 1/2" rock 6" deep. Compact the best you can. Add a 3 in. layer of a smaller rock similar to whats called traffic bond. This should give you an area that will support your pavers to be at the ground level you desire. Add paver sand under and over the pavers. Compact sand and the pavers the best you can.

Four 12x12 stones would probably be the best. MIke has a really good tutorial. Although I would probably only put the pavers after leveling with sand and set close together.
use Permasand between the pavers this will seal them and prevent any weeds from growing there.
