Campmor is a good source, and prices are reasonable. Since you want to keep out wind, I would think a tarp may not be a solution. Having said that, I have used a tarp exclusively for years on mountain trips. They make good ground covers under the tent. With a tarp, you definitely have to dig a rain trench around the periphery and one or more drain trenches to channel water away. You should also do that with a tent too.
