My apologies for a post that will surely attract the attention of spammers around the net.

Does anyone have good sources for Wordpress themes? Someone is asking me to set up a site/blog for them (for relatively little compensation), so naturally it's a theme job (and they understand that). I'm looking for someplace that curates some attractive themes, preferably ones that I can alter to fit the image of the group that has hired me.

There are a million of these sites out there, so I was hoping someone here might have had some experience with one that they particularly liked.
