I have services to offer. I'm not convinced that offering them for BC will enamour me to my clients.
For your existing clients, probably not. Will accepting bitcoins attract new clients? Again, probably not, but this is the right question to ask.
For me, trading a few bitcoins back and forth makes me part of the drama while I wait for the bitcoin economy to mature to the point where there is something that I want to do that is more conveniently done with bitcoins.
