Ask HN: Are there any high-end rentacoder type sites?

I make good money at my job, but I want to buy my own place and I'd like to make an extra few hundreds pounds a month on the side.

I've looked at rentacoder type sites, but the bids on there appear from the outset to be quite horrendous.

Are they as bad as I'm making them out to be? Do others do work on these sites? If so, what sites can you recommend, and can you share some figures?

I'm a web developer by trade: php, mysql, postgresql, js, photoshop, etc.

Thanks. :)
