Need to get new sights...

[Polo]

I have a G.I. Model Springfield and I've decided the one [and only one thing] I'll change are the sights for a three-dot style, maybe night sights.
Anybody know of a good reasonable online source for them? There aren't any 1911 smiths close to me, so I'd like to be able to drop the slide in the mail and have them put on for me and shipped back.
Must be a company that sells AND installs them, kind of like Glockmeister does for Glocks.

Thanks.
