Customer requested for a caricature as a farewell gift

We’ve put together a collage of the sort of thing we want – see attached. 
      There are 13 people to be included and four buildings  / locations (The Sportsman Pub, The Boomerang Bar, The Singapore Cricket Club and The Old Brown Shoe pub). 
       This is a leaving present for the two people in the centre of the picture (—– – superimposed on the picture of the Cricket Club and —– – the large bald chap in the centre).
         I’ll send along the individual pictures asap, but in the meantime, please could you provide a definitive quote ?  We are holding a leaving party on Dec 13th, so the completed work needs to be ready before then.
