Wednesday, I've got work til 5. Friday, I've got work til 3. Thursday I'm free all day. Saturday, I have work til 3, after which I'm leaving to go to the mountains and am not coming back until Wednesday... when I have work, again.
Any day the rest of the week after previously stated working hours is okay. If that doesn't work out, next week is okay too; I just have to find out when I'm working.
