Ask HN: Looking to buy web bases side project for less than $1000

I am looking for small websites/softwares that I can buy and (hopefully) scale a bit. This will mostly be a side project. My budget is $500 or less (preferably $300).

Anyone here willing to sell one? I am aware of websites like sideprojectors.com, but I have not found much that interests me.

Example: There was one recently looking to sell gitignore.com but I do not know what I can do better, so I am not touching it.
