I realise I'm a bit late, given the number of people who have expressed interest already, but I'd definitely be up for playing. As I haven't played one in a while, I'd be going for a good ol' classic: a half-orc barbarian.
As it looks like you've already got six players, let me know if you've got room for one more and I'll roll him up.
I've got plenty of 3.5 playing experience, and I'd love to have a go at a sandbox world, the groups I play with tend to have DMs who railroad the plot a little.
