Send them Quis and $3M.
The $3M is enough for them to buy out Quis. Quis makes about $2.5M this season, and the season is half-done so they should be able to buy him out and still have a nice chunk of the $3M left over.
What would it take at this point in the season to buy out Quis, for Quis to not lose any $$? $1.5M? Washington could use those savings to buy an earlier second-round pick next season, or just pocket the money.
We take Howard, who they don't want, off their hands. They get a little $$ by essentially buying out Quis with our money. Quis is going to need at least the 30 days to get healthy, if he IS OK by the end of the season then maybe the C's make a secondary move (buying out JO, or waiving Wafer if he's buried behind Delonte) to bring him back.
