Suit Experts: Need Help Buying a New Suit

I'm in desperate need of a new suit. I can visualise exactly what I'm looking for but am having trouble finding the suit that's right for me at my budget. I want a blue mohair suit. Two button with big lapels. Not huge lapels just not the skinny look that's in right now, I like the classic look. I have a budget of around $500 which I know isn't a lot but I was hoping to find something in a sales rack or clearance somewhere. I wear a 38 short suit which is also difficult to find though in some brands such as Paul Smith a 38 regular fits me fine. I have spoken to a few tailors and they have suggested that I check Alfred Dunhill, Pal Zileri, Corneliani, Isaia and Brooks Brothers Milano line. I have visited Pal Zileri and Corneliani and have come up short so far.

I've included a picture of a suit similar to what I am looking for.

Can you recommend brands/places I should view online or in the UK as I live here.

Any help would be greatly appreciated!
