Definitely get off the 'per-page' charging...main reason being, your idea of what a 'page' consists of can be quite different from that of a client.

I've tried going the hourly rate route, but to be honest, have found just sitting down with the client, hammering out exactly what they want/need, then providing a complete quote for the job to be the best way to go.

Don't EVER sell yourself short, or low-ball yourself. If the client opts to have their newphew who is 'good with computers' do it, they will soon enough realize the shortcomings of that. Stand strong by what you feel your time is worth, and you'll do just fine.
