Not half a job. I'm talking about search related consultations, not web design.
Some clients only need to know how to get from here to there, and for that all they need is someone to go over their site and tell them what's wrong. Doesn't have to cost an arm and a leg, and it doesn't have to take a ton of my time, either. Win-win.
Link development is a whole different matter. But even there I'm discovering ways of doing things that brings the cost down to reasonable levels- without creating unreasonable demands on my hourly rates- win-win. It's called being efficient.
Generally, there's a third way of doing things, it doesn't always have to be your way or the highway.
