Where can I get my PSP Repaired?

If your PSP breaks, like, the ons fall out, or the UMD tray gets loose, where can I go to fix it, OTHER than Sony. Is there a store that will repair for me, if I pay them? Since my warranty ended, I can no longer go for free repairs, but wha wondering what stores in Ontario, Canada (Ottawa-Gatineau Region) will repair for pay, and if there is no shop you know in that area, what types of shops will repair.
