Caricature theme - property agent

Client's brief:-
"Hi Jit,

I’m not sure if you remember me but I placed an order with you previously for our School’s Director who was leaving Temasek Polytechnic for Republic Polytechnic a few years back.

My dad’s birthday is round the corner (ok, it’s TOMORROW!) and I’d like to get a caricature of him done. Here’s some background:

 He’s a real-estate agent
 He loves his job very much
 He’s always on the mobile phone!
 (If you could draw him with more hair, I think he’d like that! 

If you could draw him with some houses in the background (mix of buildings and landed houses) along with big money signs and holding a mobile phone, that would be awesome....."
