> I noticed that the people who normally book low rate devs are the ones you REALLY don't want to deal with.
This sentiment ought to be highlighted. It gets repeated often enough on HN that some people here get sick of hearing it (search for patio11's "pathological customers/clients"). But there are always people who haven't encountered this idea, so I think it bears repeating: People looking for a basement bargain deal bring all kinds of other expectations that will markedly impact your patience/time. This has the effect of eating up any value you may have gotten out of charging a low rate to begin with.
