Questions and more Questions make the World go 'Round

Okay, so I have ... just a few questions for my research project:

Questions

1. How will we find interviewees? Legal sex workers will probably be hard enough to get interviews with (though, thanks to Clifford and Julie, we have at least one likely interview), but illegals will probably be practically impossible to get interviews with, let alone find. One possible way to get around this is to interview people who have had contact/know a lot about illegal sex workers. Also, perhaps anonymous questionnaires are a possibility, but then the question would be how we would get the questionnaires to them. Additionally, what kind of interview questions would best get at the root of our topic? What would be the best way to phrase said questions?

2. How can we incorporate technology into our study? Clifford mentioned that it seems as though many legal sex workers in the Red Light District were using their cell phones for messaging and such. Also, technology is a good way to spread information, so even if we were unable to use it in gathering the information for our study, we might want to set up a website or something of the sort to help fill any gaps in the information that sex workers have easy access to.

3. Could we include some element of observation in our study? It would be nice if we were able to do so, and thus get another perspective on the topic. Where would good places for observation be? What would we be looking for specifically? If we were looking at behavior patterns of prostitutes in, say, a health clinic, how would we identify a sex worker?
