I think Bradis will install night sites on just about anything. I'm not sure what they charge if you didn't buy the sites from them. You should jump down and ask in the Bradis sponsor forum.
Nosir, we won't. We have Certified Armorers on staff to do sight installs on Glocks, S&W M&Ps and AR-15s. For everything else, we recommend Russ' Gun Repair in Martinsville.
While the prices are pretty exorbitant, the Gander Mountain gun smith could do it. He's actually a fairly competent, reasonably nice guy, despite his place of employment.
How much do most places charge to install sights, anyway?
