One thing I've had happen with a couple of freelancing engagements I thought were promising is them wanting me to quit my day job and work full-time for them. I'd work for them for a couple of months, and then one day they would drop the bombshell that they really liked what I was doing but they wanted me full-time or not at all. I tried to convince them that it's better for everyone to have some of a good thing than none, but it didn't work, and the relationships ended quite abruptly. Two cases don't make a trend, but be aware that this can happen and it sucks when it does.
