Urgent - home needed for rescue kitten

This is a little kitten we have just rescued - it was between our wall and next door and kept retreating into a conifer tree when we got near however we managed to rescue it with the help of a friend. It had been there for around 3 days, how it got up there I don't know, maybe dumped??
Unfortunately the vet can't take it, neither can Kittens In Distress as they are both full so we don't know what to do with it now. Mickey (one of our dogs) goes demented when he sees it so it is being kept in our downstairs apartment for now but we can't keep it in this little box for ever.
Anyone looking for a lovely little kitten or any ideas please??

UPDATE: Home found!
