I have been getting my suits for the last year and a bit from Lauren at http://www.ensemblecalgary.com/.
Suits are fantastic quality and the whole process of getting measured, having a fitting session, and adjustments made after the fact are incredible.
You can go as high quality or low quality as you want as far as materials are concerned.
She outfitted my entire wedding party when I got married this past summer.
Would highly recommend her. With your budget, you would be able to get a great suit.
