As a freelancer I am putting together a strong online portfolio/website to offer my services.
I am putting the usual things in (blog/about/portfolio etc.) but I was thinking of creating a few pages (maybe password protected) that outline a lot of the questions people ask first when looking to hire you, so that I don't have to waste time typing it all out again (including my policies).
As a part of this, I was thinking of making a 'rates' page that outlined my rates.
Generally, freelancer services are not like a menu or catalog of products. You should be negotiating your rates on a case-by-case basis, based on your actual costs, financial needs, and what the client is willing to pay.
If you put down a static number, you may be saving some time on communication with clients who can't afford you, but you also don't get the chance to haggle; if you advertise $150/hr as your going rate, but can get away with a sharply discounted rate on a long contract because it's a lot of steady work, you may lose clients that never even talk to you because they can't afford $150/hr for the 6 months they think something will take, when really you'd accept half that or less because you know where your next meal is coming from.
Instead, I would simply advertise "competitive rates" and that can be a negotiating point.
