How do i find a good reliable programmer?

I'm looking for some minor customization to be done on a jquery plugin but from all that ive read ill have to sift through a sea of bad programmers just to find one good one. I dont really have the resources to do that, does anyone know of a site where i can find a reputable freelance programmer to do a small job?

I suppose while im here, if anyones interested:
