Ask HN: What are my options for interviewing and negotiating advice?

I am currently approached by a startup who wary of working with me because of schedule conflicts from my university courses. They would like to know how much money I am expecting for this job. Of course I have many questions for approaching this. Should I offer to work hourly? Should I 'pro-rate' my salary accounting for the hours I would be available to work? What kinds of arrangements can I expect will be suitable for a similar company?

What I would really like to know is: Aside from posting here, I think the general audience would like to know what resources are available for working through this. Are there companies who provide this? People in the community?
