The way the company I work for does it is we say

Web design from xx

CMS from xx

I think this works a bit better than giving a sort of price list so people can get an idea of your pricing, but you are not really giving a set price and are still able to price on a project basis.

Thanks for the advice folks, much appreciated

Thought you could escape me? Mooha-ha-ha!

Dizi's 'from' strategy is a good one, on my up-coming site revamp (sneaky-peek http://wizelysworld.me.uk/vividcopy/copywriting-services.html?copywriting=copywriting-rates) I'm going for an average price per page that a client can expect to pay, a typical range and illustrating it with an example. I'm also showing the prices for 'the full monty', for the equivalent of a new design and for a redesign. There's even a 'from' price in there.

Sure every job is different but from experience I know what my average rate is for something and also the top/ bottom rates. It still gives the flexibility to create an accurate quote on each job, but showing an indication of prices is always a great idea if you can. Not showing prices gets on a lot of folks' nerves, it requires them to go to more effort to get answers and means you're open to time-wasters who want the moon on a stick for 20p!

No single approach works for every one, but the more information you can give prospective customers then the less questions they have unanswered and so less reason to continue searching elsewhere. 

I have found that what works best for me is to have the prospective client contact me for a quote. I dislike being in the position of having stated a price and then having to vary from it. Clients that I've tried to do that with in the past have attempted to 'hold me' to the initial guesstimate. I try to avoid anything that will lead to a less than positive rapport.
I think it will also depend on a couple of different things. Including your comfort level. One thing to consider is the method you use to obtain clients. If its primarily web based, it may be wise to shop your competition and take a look at how they present their offerings. If a fair number of them leave it contact only, this can be a good thing, because then you don't have to compete with them on pricing if none has been stated anywhere. Conversely if a fair number state a price, you may feel comfortable leaving yours within that range and making it visible.
If you obtain clients via a more direct marketing medium, I would certainly not leave them with a price list! I'd take that as the opportunity to give them a quote based on their exact needs.
As with all ymmv

I think thats great advice, plus it comes from someone with a  good reputation in my opinion

Wow! Thanks for those kind words (cheque's in the post!). Well, in this one thread I've managed to create a digital persona on this forum that's just asking for a cricket bat in the face! Unintentional I promise - just trying to give good advice - I much prefer my reputation to be one of smut-peddler and harasser of female mods (and ex mods)!

I've now "pulled the trigger" and launched the revamp of Vivid Copy and you can see the http://vividcopy.co.uk/copywriting-services.html?copywriting=copywriting-rates in action as it were.

Oh don't worry Wizely, we all know that's the real you. It's only your public persona that is all kind, professional and giving!

I like the idea of a fixed price list that starts at your mid point, ok you may not get as many enquires but if you quote under your starting point you may convert more.
