Can any OB/GYN perform intrauterine insemination?

I've decided I want a second baby but being single now I am going to use a donor. For my first baby I used a midwife so I don't have a doctor I have a relationship with that I could easily ask. Do most OB/GYNs perform intrauterine insemination or do I have to go to a fertility specialist? Do fertility specialists only perform invitro fertilization? I'm looking to (hopefully) become pregnant fall/winter 2011 so I would like to start talking to a doctor now I just have no clue who to talk to. Thanks!
