As I normally would, I went straight to the IT Section > Web Design and I found hundreds of jobs, most of them are small 4 page website projects that the client wants and are only willing to buy for between $250-500, but there was one that stood out, this client wanted an ASP.net developer to update and upgrade the website for $2000.
