We were in the same situation recently. We looked for programmers in specific programming/framework forums (ie. Cake Forum, CodeIgniter Forum since we are using PHP framework). After receiving a bunch of applications/resumes, we filtered out to the ones we think are good, then we phoned them and had a chat. With the Internet, you could use video conferencing programs like samratjp suggested. In our case, we were lucky since I was on a trip to where the programmer was so we actually met up before hiring. Anyhow, good luck with the hiring!
